Cast blast paint for exhaust manifolds
Did a forum search for what paint would look good on my drive shaft and half shafts, and Seymour Cast Blast seems to get a lot of votes. I'll get some.
Then, as a separate project, I'm looking at their high temp stuff which I could put on the exhaust manifolds. But they say it needs to bake at 400 degrees for at least 2 hours. I have a patient, understanding wife, but I'm not THAT stupid! :hide: What do you guys do for stuff like that? |
POR15 exhaust paint

Hi-Temp Cast Blast is the way to go. I've used it on at least a dozen cars with no complaints. I just let the heat from firing up the engine cure it. Here's a pic of my 65 BB after curing the exhaust. The manifolds on my 60, that I did 30+ years ago with Cast Blast, still look just like this.https://cimg7.ibsrv.net/gimg/www.cor...3262b12dc8.jpg

I should add I'm a long way from firing the engine, have not even torn it down yet. Trying to get ahead of the game by doing the manifolds and setting them on a shelf. I guess finding some hot rod guy with a kitchen oven in the shop is the best option. Or maybe browse CL for one of my own but that seems like overkill for something I won't do very often.

All high temp paints should be control heat cured prior to using in anger. They will last significantly longer. if you have the room, I bought an electric oven from Craig’s list for $25 because only one of the stove burners worked. He even delivered it to my house. I use the oven to cure powder coating, high temp paint, and to clean parts (it’s amazing how well ez off oven cleaner works on greasy parts when you have a little heat). Prior to that I had a toaster oven I got for a few bucks at a yard sale. You might luck out and find a toaster oven big enough for your manifolds. They work great for curing high temp paint, just make sure you preheat them first. |
I used Seymour Cast Blast, and cured them in the bbq grill, with the outer burners on only, and the manifolds in the center. I figured the thermometer in the hood was close enough. I think they came out looking pretty good, but I haven't run them yet.

Here are some options side by side for you that I just happen to have on hand, but I am not going for judging or anything....https://cimg4.ibsrv.net/gimg/www.cor...3e168810af.jpg

You are talking about pre-heating the oven, not the work product, correct?

I have used this before with good results. I like the brush on so you can get in tight places without runs. |
