Jim 123 Posted October 9, 2018 Share Posted October 9, 2018 Google "Glasurit Technical Bulletin clearcoat carbon fibre". This will lead you to a PDF with process instructions and materials for both standard or high end appearance. Link to comment Share on other sites More sharing options...

Jim 123 Posted October 10, 2018 Share Posted October 10, 2018 If you go for a new CC part check first if it will be delivered clear coated. I suspect it will not. Link to comment Share on other sites More sharing options...
SpeedPete Posted October 11, 2018 Share Posted October 11, 2018 The best product to be recommended depends on how you intend to use it and what you expect as a result. If you just want to protect an existing cfrp part and take the easiest alternative, I'd use the 1-component TRISTARcolor clear coat which is delivered in a spray can. Very fine distribution of the particles in the air and large spray volume. It's also somehow leveling the surface when it dries and with this correcting a bit mistakes made when applying it, other comparable clear coats I know do not show such a behavior.High quality results require 2-component applied with a professional spray gun. Those guns are expensive, though. And if you make a mistake, you won't get it off again easily to start from scratch.Then there are epoxy gel coats which are the most resistant to scratches. Not that easy to apply, though.I've made good experiences with this: https://shop.hp-textiles.com/shop/en/covering-system-gelcoat-epoxy-resin-hp-e25dm.html . It's low priced and didn't create any troubles. I can't tell about the long-term UV stability, though. The resulting products haven't been exposed to extreme UV conditions over long periods of time yet.Peter Link to comment Share on other sites More sharing options...

Leadership Team SLR No.77 Posted October 11, 2018 Leadership Team Share Posted October 11, 2018 Steve, any CF parts that you clear coat will be more easily damaged by stone chips than the original non-coated CF panels, it is therefore wise to limit the clear coat application only to areas that will not sustain damage. Cycle wings should be fine, but if you have the nose cone (or just a front band) clear coated it would be wise to add paint protection film to reduce the stone chips. Rear wings are only worth doing if again you're going to use enough paint protection film to cover the forward facing surfaces and round the outer edge. Think of it basically as clear paint.Stu.

Brightonuk Posted October 11, 2018 Author Share Posted October 11, 2018 It was just the dash, but CC no longer makes one for my car, the three indicator lights between the rev counter and spoedo will not fit so I guess I will need to reposition them elsewhere or look to a alternate supplier, the issue with that option that is I had a bad experience with Carbon wings from KCD. The quality/finish was not really up to scratch, and being states side Its not like I can return them.I want the dash finished like the CC one not dull and needing polishing and coating apparently that is a 2x2 (twill) weaveWestermann make one that has a great looking finish but way expensive if you want cutoutsUC Has mine but the finish looks dull and unfinished Link to comment Share on other sites More sharing options...
TomB Posted October 11, 2018 Share Posted October 11, 2018 Wouldn't the best approach be to lightly sand and then re-lacquer? Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted October 11, 2018 Leadership Team Share Posted October 11, 2018 Steve, do you already have a CF dash? Is the condition poor?The later cars have the 3 lights located within the rev counter enabling the rev counter and speedometer to be positioned slightly closer together to give a better view of the gauges through the steering wheel. Also the radius at the bottom edge of the dash differs on later cars so would not fit.I'm pretty sure all the Caterham dashboards are 2x2 twill weave but the current versions have the carbon fabric laid up on the bias giving the "vertical lines" appearance.Stu.

Brightonuk Posted October 11, 2018 Author Share Posted October 11, 2018 Yer that's the plan now I guess, I will give the sanding and re-lacquering a go, worst case I screw it up it looks crap and I get the CC one, relocate the indicator lights worry about the next thing.

Jim 123 Posted October 11, 2018 Share Posted October 11, 2018 For a dash, which I assume you will be doing at home, stick with the Premium Finish instruction in the Tech Bulletin which Anthony provided the link for, and apply multiple layers as directed. If you don't have access to a large enough oven the Product Data sheets will tell you how long to leave between coats. Lay the dash flat for spraying and keep dust to a minimum. You will achieve a finish that will be as good as anything on a Bentley. As you have observed the process is labour intensive, which is why Class A surface clearcoated CF parts are expensive.

Simon.Rogers Posted October 12, 2018 Share Posted October 12, 2018 Westerman carbon id not full carbon. Its composite - wet lay with GRP strand in the middle.It is generally good to look at but just so you understand its not Pre Preg. Link to comment Share on other sites More sharing options...
Jim 123 Posted October 12, 2018 Share Posted October 12, 2018 An off the wall thought........................If you are only wanting to recover the appearance of your dash without a lot of hassle, what about removing the instruments etc. prepping and applying a layer of clear stone chip resistant film as a gloss finish to the dash? I am conscious that the original finish, plus the temperature and humidity cycles in your part of the world may undermine this as a durable durable solution, but you could try fitting a couple of small test pieces to the in-situ dash to validate.

Brightonuk Posted October 12, 2018 Author Share Posted October 12, 2018 Wow and for 400 quid thats rather expensive?Either way I am going to try to do the DIY option I will post some before and after photos Link to comment Share on other sites More sharing options...
Brightonuk Posted October 15, 2018 Author Share Posted October 15, 2018 So the result I could not source the Glasurit that Jim suggested but found this alternative that requires a hardener (which is in the can but has to be activated) I was originally going to try to mask the dials and switches but ended up removing everything and sanding the dash with 1000 grit wet n dryAfter 18 years there was not much lacquer left on the dash so I did not need to be too aggressive Here is before: Sanded Taped and readyI gave it three coats and of course due to my inexperience went too heavy on the first causing runs in a couple of places not terrible but would not pass a Ford QC.Another step I did not do due to my impatiences to finish the job was to sand between coats I think it would have provided a much better finish.Anyway here is the result not perfect but an improvement over the original I also did some test sprays on the tip of the nose which was in a terrible state (see the previous post on "a crap respray" for the full SP)Before Here it is after one coat.I will take more time over this job as I also need to lacquer the new KCD cycle wings that look unfinished and the dash was a learning process Bottom line this was a cost effective way to bring back tired looking CF not perfect but well worth the effort and I think with what I learned from the dash re spray the wings and nose will have a better result.

Leadership Team Mcalvert Posted October 15, 2018 Leadership Team Share Posted October 15, 2018 That looks great! (Mind you, judging by the warnings on the can, it must contain some "good stuff" ) Link to comment Share on other sites More sharing options...
TomB Posted October 15, 2018 Share Posted October 15, 2018 Brilliant, please can you post a link where you bough the spray from. Just what I need to do to mine. Link to comment Share on other sites More sharing options...
Brightonuk Posted October 15, 2018 Author Share Posted October 15, 2018 Amazon Link 12 bucks was a bargain compared to the cost of a new CF dash https://www.amazon.com/gp/product/B0043B7UQY/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1Heres a short video of the stuff being applied by a pro Link to comment Share on other sites More sharing options...

Jim 123 Posted October 16, 2018 Share Posted October 16, 2018 Frosts in the UK do a 2K aerosol by Eastman. It should be comparable in properties. If it doesn't say so on the can, it is best to wear a protective mask when using these products as they contain isocyanates which have a cumulative and lasting effect on the lining of lungs Link to comment Share on other sites More sharing options...
TomB Posted October 16, 2018 Share Posted October 16, 2018 https://www.frost.co.uk/brands/eastwood/2k-aero-spray-high-gloss-clear-14148.htmlThis I presume? Looks an attractive product for rejuvenating an older CF dash. Link to comment Share on other sites More sharing options...
Jim 123 Posted October 16, 2018 Share Posted October 16, 2018 That's the one Tom. I still think it would be interesting to see if a dash can get it's appearance back by applying a layer of stone chip clear gloss film. Unfortunately I don't have a CF dash to try applying a sample to see if it works. Link to comment Share on other sites More sharing options...
