ormplus Posted June 21, 2011 Report Share Posted June 21, 2011 washing it with gunk would be fine,then give it a wash with brake cleaner to make sure all the oil is removed them paint. Quote Link to comment Share on other sites More sharing options...
charliechitlins Posted June 21, 2011 Report Share Posted June 21, 2011 Blasting is tricky...especially with glass beads. It only takes a few to ruin an engine. After blasting, I wash everything with warm, soapy water, dry immediately with compressed air, then paint. Now...many high temp paints need to be heated quite soon after applying, AND they come off easily when handling before curing. So whipping the top end right on and starting the bike can be a problem. I heat parts with a propane torch, apply the paint and heat again. You can see it cure. Quote Link to comment Share on other sites More sharing options...

Also, PJ1 paint does not need to be heat cured - it cures to a durable finish overnight. Cheers, Max Quote Link to comment Share on other sites More sharing options...
