Tyrone Posted November 1, 2011 Share Posted November 1, 2011 There are plenty of threads for removing paint from carbon fibre, but I couldn't find any for painting it. My RiF cycle wings suffer from the horrible milky pattern staining caused by water, so I am going to paint them black. How do I prepapre the wings for paint, which primer, etc.?

Area Representative bluenose Posted November 1, 2011 Area Representative Share Posted November 1, 2011 Have you tried wiping the carbon with 3 in 1 oil or WD40. just a little on a clothe goes a long way. It brings my carbon up nice and black with a good lustre. Nick Link to comment Share on other sites More sharing options...

6speedmanual Posted November 1, 2011 Share Posted November 1, 2011 Stop! Assuming you like the carbon weave appearance, try cutting them back hard with T-cut metallic. (slightly less agressive than normal) Then polish with AutoGlym Super Resin Polish (less abrasive again) Finally, try protecting with 303 Aerospace Protector. Can be bought on Ebay. I have been using this since I posted on this thread --> here. Designed to UV protect aircraft finishes and nylon microlight wing fabric. Each time I wash the car, I dry and spray on/wipe off a fresh dose. Product goes on very smoothly. Almost no shine up required, it seems to self shine when wiped on. Deffo leaves a coating on the surface. So far, water spots have not caused further white staining. The only reason I have not yet updated on that other thread is that I don't feel I've given it enough "field trial" yet to offer a recommendation. I would hold off painting just now. I'm sure T-cutting and then treating with the right protective product can stop this problem. Cheers Peter Link to comment Share on other sites More sharing options...
Tyrone Posted November 1, 2011 Author Share Posted November 1, 2011 I have tried any number of bumper/ back to black type products including one which Richard sent me when I had the same problem with my aero screen. I'll give Peter's advice a try before I paint. I'll keep everyone posted. Link to comment Share on other sites More sharing options...

Stationary M25 Traveller Posted January 14, 2012 Share Posted January 14, 2012 Another recent thread suggested using Wood Silk - a household wood polish available cheap from supermarkets. Cap of can looks like a yellow beehive. Stunningly effective on my carbon Link to comment Share on other sites More sharing options...

Unclefester Posted January 16, 2012 Share Posted January 16, 2012 Tyrone, why on earth don't you just get them sprayed with a good clear lacquer? Something like DuPont 2-pack high solids clear. This should get rid of the staining and permanently seal them, giving a really glass-like easy-clean surface and enhancing the appearance enormously. You should give the surface a good clean with petrol, or pre-paint degreaser first, specially if you have ever used silicone based stuff on them, or wax. I have never understood why the manufacturers don't do this as a matter of course, particularly as these things are largely cosmetic, if we are being strictly honest.

Leadership Team Mcalvert Posted January 16, 2012 Leadership Team Share Posted January 16, 2012 Would be interested to hear of anyone who has successfully done this on "old" CF. I spoke to TSK about lacquering my front wings a couple of months ago, but the feedback was that although it would look great for a while, because it is difficult to get an adequate key onto the existing material, in time the laquer would start to peel.

Mark w Posted January 16, 2012 Share Posted January 16, 2012 I got some rubbing compound from Carbon mods . Lots of careful hand polishing brought back the appearance , i then got it ( nose cone in this instance ) laquered . No problems , keeps shiney and hasnt peeled ( yet ! ) Cost less than £5 for the compound and £40 to get the nose cone laquered . Link to comment Share on other sites More sharing options...
Tyrone Posted January 17, 2012 Author Share Posted January 17, 2012 it is difficult to get an adequate key onto the existing material, in time the laquer would start to peel. Would the same not apply to paint too? A lot of carbon nosecones are painted, do they peel? Link to comment Share on other sites More sharing options...

Michael. So you use an etch primer under the varnish....this is also used on aluminium to key the surface, as it's acidic it removes the micron thick layer of aluminium oxide. I haven't ever tried this on carbon fibre, it'd be sensible to check or experiment with a broken bit of CF to see what effect the "wash" etch solution has. It might promote some nasty reaction with the CF. I think a safer bet is the "adhesion enhancer" coat often used on plastics.This is not unlike a fine spray glue coat. I would think personally that a good light sanding with 600 grit wet'n'dry would allow a GOOD 2 pack clear coat to adhere perfectly well. Some clearcoat is rubbish. In any case it wouldn't look any worse than the horrible mess CF becomes when the water gets to it. I have a knackered CF wing here I can try this on. I think painting CF is an admission of defeat.....adding weight to cosmetically change something which you've paid a lot of money for which is supposed to be cosmetically interesting in its own right..... Better add clearcoat, which is, after all, just clear paint without pigmentation, and at least keep the cosmetic aspect of the CF at its best. Personally i think it looks far better under gloss but then I'm a pleb. Edited by - Unclefester on 18 Jan 2012 18:38:03 Link to comment Share on other sites More sharing options...
