I am using Rustoleum high heat bbq paint, I followed their recommendation of curing 2 hours @ 300 degrees only to have my rag turn black when I gave it a light oil rubbing. Will longer and hotter help?

Thanks
Tom

I used Dupli-Color High heat ceramic paint on my build. I don’t know about Rustoleum but from my understanding it sounds like you may not have prepped the metal very well. The new finish needs something to stick to. I used a scotch bite pad to scuff up the finish then I hosed the parts down with brake cleaner and let them dry well before painting. Then I baked the parts at 400 for an hour and a half. For $5.00 I can’t complain.

Thanks for the reply Sign_Wolfman, I just degreased with brake cleaner so I guess I will strip it down and retry.

you cant use rustoleum no matter how good of a job you do it will come off with light oil

use krylon bbq at 400 for hour and 15 you will be much happier with the results

Try Rustoleum textured enamel, prep it good and bake at 350 for 4 hours. Oil won't touch it.

+ 1 on the Krylon BBQ. I have tried several "Rustoleum" products, they usually got gummy or wiped under oil.

One finish I did though with Rustoleum that came out sort of neat was thier "black" hammered finish. It actually isnt black, it is more charcoal grey and closely resembles the finish on the PSO-1 scopes, very close.

I too would like to know what is the best coating I could lay down on a blaster without going the Dura coat, Alumahyde, gun kote route.

I am a cheap a$$ and also would like to pick it up locally as opposed to mail order.

How does the Krylon paint hold up against a mild solvant like Hoppes#9?
Link Posted: 12/21/2005 4:53:55 PM EDT
it holds upto most solvents
and small amounts of brake cleaner

ie if you clean your bore with brake cleaner its not gonna hurt the finish
if you hose down the side with brake cleaner and start rubbing it will start to come off
but so will almost every other finish including moly and gk

Thanks again for the help, I will give krylon a try, it's too bad about the rustoleum because I really liked the color and texture of it.

For me, the ultimate test of any spray on finish is Gunscrubber or acetone. If neither of those two will soften the paint, it's a good finish. Not many hardware store paints will pass this test.

The alternate and not as stringent test is to take a cotton ball soaked in whatever your usual bore cleaner is and wrap the wet ball around the finish. Leave overnight and check the paint.

BTW--AlumaHyde II passes both tests.
