Exhaust paint/coating.

[Spaarky]

I uncovered the old girl yesterday. I was going to clean the clutches and get it ready for the year. I was reminded that all the work I did a year ago, was a waste. I cleaned up the exhaust, repainted, wrapped the pipe, and got it all cleaned up.

By the 3rd ride the paint was flaking off the y-pipe and a few other parts. It was the second year in a row, I had painted things up. Last year I used a high temp primer and paint, from the local auto parts store.

Does anyone have a suggestion of a brand or something I can do to possible make it more than 3 rides? I was going to send some of the parts off for coating this summer, but it was busy and I forgot. No time to send them away for coating now. I would imagine by the time they get shipped, coated and sent back, it will be 3 weeks to the month.

Thanks.. for any suggestions.

I've always had great luck with auto parts exhaust paint or grill paint. When you say your wrapped it, is this a high temp wrap? Generally a bad idea because they hold moisture in. Works fine on a car because they don't get exposed to moisture. I also never used primer on my pipe. I couldn't find high enough temp, so cleaned up the pipe with a wire brush and electric wheel, then cleaned with mineral spirits and then sprayed over the remaining.

VHT Exhaust paint.

I've been using the 1400 degree high temp paint from Ace Hardware with goo results.

Typically paint peeling is an indication of an adhesion failure....the coating will work best if it has the best prepped surface possible. I have always prepped pipes by decreasing them and then sandblasting them to remove all old coatings and rust. Not sure if you have access to a beadblaster or local sandblasting company, but this is the best way to do it. I have used several different types of high heat paint and they all have held up quite well. All have been direct to metal coatings - meaning no primer required - just a couple coats of the high heat product. Follow the directions as best as you can and if you can pre-bake in the oven prior to installing is even better(wife might kill you after it stinks up the house...!). The other lesson that I've learned is that to try use a fine blast media - if it is quite aggressive, it creates a blast profile that requires more coats of paint to cover. Hope this helps.

If you use the oven for food consumption do not bake paint in it.

I read in my paint can that you can warm up the motor with the pipe/exhaust on it.

I cleaned up the portion that is showing again. The y-pipe is the worst. Cleaned it with the same cleaner painters use right before painting. I used the VHT paint. See how it works.

I think last year, I used the DEI, silicone hi temp that I used on the pipe wrap.

Give it another shot. If not, next year it might go out for costing. I am picky and it drives me nuts.

Last year after I was all done, I took it to the powder coater and had him through it in the oven.
Thanks for the suggestions!!!!!
