exhaust pipe rust/paint
Starting to get some surface rust on my exhaust pipe after the muffler- I want to get the rust off and paint the pipe to hopefully keep the rust from coming back. Can anyone recommend a good paint? I hear the exhaust temps from the diesel engines are really high so I would like to get the right paint- does anyone make an exhaust paint that will help keep the rust down?
thanks!
Steve

The paint that a lot of us classic and hot rodders use is VHT (Very High Temperature) which is a ceramic coating. See www.vhtpaint.com
I have used another product called Cast Blast on my exhaust manifolds. It is the same basic type paint as VHT but it is the color of new cast iron. Works on exhaust pipes also.

Good old BBQ black High Heat by Rustoleum. Every few trips I shake rattle and spray the tail pipe. Looks great when I pull into the RV park.

Throw a stainless tip on it, then you never have to worry about it again. BTW they look great too!

The VHT is good for 1300 or 1500. Forget which it is, but you can get it at just about any automotive parts store.

All of the paints recommended will coat the tail pipe and look great for a few months and then the rust will come back. If you want to do it once, get POR15 high temp/engine paint. I did mine several times with the VHT and then used the POR15. It has been on for over a year and still looks great with no rust. More expensive but worth the final result!

I used gray because that was what I already had. When I painted it I was just trying to extend the life until I could find a stainless tip to fit the rectangular opening. Don't think I will ever have to replace it now. For information, I used the regular black POR 15 to coat my battery racks/trays and floor in my electrical cable box. This stuff is very durable and worth the cost but make sure you wear good rubber gloves because as soon as it sets, it is there until the skin wears off and the nails grow out.
