andy couchman Posted February 8, 2010 Share Posted February 8, 2010 One of the problems with exhaust wrap (as I understand it) is that the tape can absorb water. This can lead to problems with the exhaust pipes underneath. I read somewhere that the thing to do is paint the tape with high temperature paint once installed. Question: do you put the tape on and then paint it? Or put the tape on, run the engine to 'cure' it (lots of smoke ) than take the pipes off and paint it?

dalongbloke Posted February 8, 2010 Share Posted February 8, 2010 If this is for a 7... I assume it is... we have stainless exhausts. There should be no prob if the wrap absorbs water. I leave mysself open to correction by the POBC.... Andy Check out Hal... http://picasaweb.google.co.uk/dalongbloke Link to comment Share on other sites More sharing options...

andy couchman Posted February 9, 2010 Author Share Posted February 9, 2010 Hmmm. Thanks guys. Mine runs stainless pipes too, but take the tape off and the pipes look a bit rough - not exactly rusty, but not great either... It's certainly simpler to leave the tape unpainted Andy Link to comment Share on other sites More sharing options...
paul jacobs Posted February 9, 2010 Share Posted February 9, 2010 I've had the wrap, unpainted, on my CSR since I built it in 2006 Andy, and whilst I haven't had it off to check the metal underneath, all seems well as far as I can see. Any water that gets onto it [mainly from the hosepipe when washing admittedly], steams off within minutes of the engine starting. If it were to be parked up in the open for any length of time of course, it could be a different matter! A little tip here, you can buy massively expensive stainless steel 'tie wraps' from the wrap supplier, or you can get the same things at your local builders merchant for substantially less, or just put a few rounds of copper wire around it and twist the ends, it gives that lived in look 😬 Paul J.

Drumster Posted February 9, 2010 Share Posted February 9, 2010 Likewise. I put Cooltek wrap on my x/flow's primaries in 2003 and when I rebuilt the 7 in '08/'09 the primaries were discoloured but I'd say no more than if they hadn't been wrapped.

John Howe Posted February 10, 2010 Share Posted February 10, 2010 Like those who have already commented... I've had my primaries wrapped for six or seven years now. The important issue, for convenience of clean fitting, is to buy the tape that need to be dampened prior to fitting. This tape can be teased around a corner, which in turn stops the unsightly lumps caused by excesses... as Thomas Rosselle found out last weekend. Because the tape is damp, it needs to be allowed to dry before spraying it with heat paint. However, don't make a shopping trip your first outing in the car, as once the painted wrap has been fitted it will smoke a fair bit for the first few miles and sitting at a set of traffic lights billowing smoke through the bonnet vents will raise a few eyerbrows.
