Painting Cylinder?

[chee001]

I would like to repaint my cylinder for my 70. Would it be wise to get it sand blasted then spray paint the outside only with high heat primer then high heat glossy? I also plan on getting it reboard for a new piston.

Sandblasting or media blasting would be fine. Follow that up with a good degreasing. I think you will be fine with just the high temp gloss black, that is what I used.

Is the paint holding up well without a primer coat?

I wouldn't prime it myself, when you build up extra paint on the fins it won't cool as well. Just my 2 cents worth. good luck with it.

Painted mine with header paint, no primer. Holding up well.

It should be cleaned first, then bored, then painted. The people who bore it should do the cleaning for you, the things I've had machined before were always cleaned before they did any machining, if the items needed it of course. You will need to clean it well after the machining is done too. As far as primer goes, I've never used heat primer and I haven't had any problems with the dozens of parts I've painted, the heat paint sticks just fine. Thats my :4:

No primer...Just High Temp Paint. Grant's right, you do not want a lot of build up on the fins.

Thank you guys very very much!!

when you say high temp are we talking 500 degree engine paint or 1200 degree header paint? I don't think I have seen gloss in the 1200 stuff.

500 should be plenty.

Whatever you use, I would go light with the paint. After all, the cylinder is designed to transfer heat.
