Hey I was wondering whats the best way to paint a aluminum block as far as materials go and procedures... I am just waiting to paint the block and want to know what primer etc base will hold up the best. I want to know the best rattel can and best spray gun products.

Thanks Mark Tisdale

VHT High Temp Engine Block Paint from any auto parts store. 500 degree should work just fine, but they also have a 1200 degree version should you feel the need to use that. They have a wide range of colors too. No need for primer also, just degrease, tape off bores/deck and spray.

I was thinking on painting it orange, red, or black...

I have always had good luck with the duplicolor 500* stuff. The key to good results is in the prep. I always degrease the part, hit it with a red scotchbrite, and then wipe it down with laquer thinner.

I've never painted Aluminum..it hinders its natural ability to disperse heat.

I thought the paint itself wouldn't stick well to the aluminum.

It's just an air filter housing.

Powdercoat it. LOL

I wouldnt want to paint it either but it sucks when aluminum gets that chalky oxidized look to it.
