Paint Spec for 74" Jugs

[brian_groff]

Does anybody have a good recommendation for painting the cylinders/fins on a Chief engine? (or any other cast jug for that matter).

Best solution I've heard is to sandblast 'em, machine 'em as needed, then put 'em in the oven to bake out moisture before painting with regular gloss black krylon.

Curious to know if anybody has a solution for higher heat dissipation.

I bought an Eastwood powder coating system this year and am very happy with the results all around. They have a high temperature coating in black and silver. These are "siliconized".

After the prep by bead blasting, I wiped the cyclinders several times with SEM degreaser/dewaxer. THe powder is easy to apply, and it cures in a 400 f oven. I got a free oven out of the local paper.

All the parts I did came out nice. Unfortunately, I only have about 1 hour on the cyclinders, so cannot give you a long term report yet.

With the powder coating, is there any noticeable increase in engine temperature? I would think the powder coating would tend to insulate the jugs and reduce the efficiency of the fins.

The product from Grainger sounds like it's fairly proven. Did you bake the jugs in a regular cooking oven?

cylinders

hi brain i had picked up an old junk oven from the newspaper and baked them in it. it does stink a little but the finish was perfect not to flat or to glossy just right.
