Thread: Paint for motor

Tweet

I want to use the same color paint for my motor that I am using for the body on the car. My question is, if I use the same paint for the motor that I use on the body will it stay on? If not what do I need to do to the paint so it will stay on the motor.
Thanks

I've used some various single stage paint on motors, Centari and Concept among them. They seemed to work fairly well. I'm considering a hi temp powder coating on the Nailhead...

I painted a 454 with a blower on it white one time with the same acrylic enamel paint I used on the car and 2 yrs later it still looked good. That blower really gets hot.

Most pieces are sand blasted as part of the powdercoating process. If you go this way, make sure you get every bit of sand out of the motor, or you could have major troubles! I wouldn't chance it. I don't think you have anything to gain with powdercoat.

Thanks guys

I wash the heck out of my engines with hot soapy water and good bristle brushes (down all the oil gallies too) before they go together anyway. A friend of mine has started a powder coating biz, he wants to do the Nailhead for the advertising. Thanks for the advice Paint. I'll be sure to give it lots of extra scrubbing.

Hotrodpaint, you are kind of correct, we have parts powder coated weekly without sandblasting......we do sandblast the welded steel tubes that have mill scale and rust on them. The structural steel has a lot of dirt, oil, and grease on it too that the sand blast removes.

For the parts that are relatively clean to begin with and for sheet metal parts, they dip them in a cleaner/degreaser. IF a block has been hot tanked, it may be powder coated EXCEPT that, if there is any amount of oil on it, the powder coating will bubble where the oil outgasses. This especially happens at threaded holes and crevices where the oil is trapped. One helpful step is to pre bake the item in the oven for several hours before applying the powder. This either vaporizes the oil or boils it out where you can see it and wipe it off with solvent. Some items with mass need to be preheated and then coated hot since heating a cold part would result in uneven powder reflow.

Touchup on powder coat is a bitch.
