dav a Posted August 11, 2014 Share Posted August 11, 2014 Hi all not sure if this is the right place for this please move if not. I have got myself an old twist and go to keep the miles down on the Midnight star ,the problem I have is the header pipe is starting to corrode ,I have tried to protect it by removing the loose rust and painting it with high temperature paint I have done this twice now and both times the paint has burnt off in a matter of days . The paint I used is Halfords own brand, am I doing something wrong ,Ive tried increasing the temperature gradually but it still burns of ,is there a better brand or is a downpipe just to hot for any paint. any suggestions appreciated . Cheers Dave Link to comment Share on other sites More sharing options...
AndrewElvisFan Posted August 11, 2014 Share Posted August 11, 2014 I used hammerite BBQ paint a few months ago and it's still holding now Link to comment Share on other sites More sharing options...
AndrewElvisFan Posted August 11, 2014 Share Posted August 11, 2014 Did you use a rust paint first to harden the corrosion? Link to comment Share on other sites More sharing options...
Moderator Airhead Posted August 11, 2014 Moderator Share Posted August 11, 2014 andrew did you use hammerite BBQ paint? I use plasti cote BBQ paint from B&Q or Wilkinsons, needs curing first though I leave it on the works boiler for a week Link to comment Share on other sites More sharing options...
slice Posted August 11, 2014 Share Posted August 11, 2014 I use UHT paint from the local car shop and cured it with a hot air gun for about 15 minutes, it chips a bit from road grit and stuff but to be honest if you just slap it on and don't cure it then it will peel off.

NE0 Posted August 11, 2014 Share Posted August 11, 2014 I used Plasticote BBQ paint on Airheads recommendation on my DT's exhaust pipe. However, within 6 inches of the cyclinder head I find it tends to burn off after a few months. The rest of the pipe is fine, I just re apply it when it looks a bit tat! The cylinder head was painted with Simonez Engine paint and has lasted well on the aluminium however, it too burned off from the first 6 inches of the exhaust.

It's about all you can do is to keep on top of it. 1 Link to comment Share on other sites More sharing options...

'Hot Paint' Used it at the exhaust start, let the exhaust heat cure it. Link to comment Share on other sites More sharing options...
neversaydie Posted August 11, 2014 Share Posted August 11, 2014 Just done the collector box on the virago last week, hammerite, but wire brushed all loose off first, then used one of those rust convertor liquids (cant remember the name at the mo), its all still on Link to comment Share on other sites More sharing options...
dav a Posted August 12, 2014 Author Share Posted August 12, 2014 Hi all thanks for the replies,I used a rust cure the first time{,its some sort of acid that turn the rust black ] thought this was the reason the ht paint didn't last second time just paint on bare metal .think I might try BBQ paint see how it goes.
