Painting Cold Metal?

[stoney1964]

I am hearing that its not good to shoot cold metal? Help my ignorance, please. I am not too savvy on the paint dept. I seen at the local hardware today that Rustoleum carries an automotive primer. Any objections to using that on my ride? Thanks

Need to have that metal warmed up good. Ideal temps to spray paint is 65 - 75 degrees. Been at it an awful long time.
Rustoleum primer is fine for some things. If it was me I would choose a good Epoxy primer. Hope this helps. TR

Can I get epoxy primer in an aerosol or have to hvlp? I am interested in spot priming without having to load gun. Thanks

For temporary protection yes, but most primer in aerosol cans isn't really too good to paint over. A shop would want to strip it all off and start from bare metal. Aerosol cans are almost 70% propellant.

Just depends on what your final result is going to be and whether you're doing the whole thing yourself or just part of it.

So, being the amateur, it is recomended to use an epoxy primer out of the bigger paint size cans found at the auto parts store with the compressor as opposed to the tiny spray cans when priming and painting?

Duke.
For brackets, small parts and valve covers and the like, I've had good success with the high temp ceramic rattle can primer from places like AutoZone.
For black parts I use the appliance black epoxy from Lowe's and Home Depot.
Other colors in the ceramic paint line seem to hold up well for small parts.

Yeah Skip, stuff like that is fine. I wouldn't want to have to fill up a gun just for little parts. Small parts like Skip mentioned are fine with those. If you are spot priming on bodywork you might want to try the Duplicolor primer sold at ORielly's and other stores. It is a little over $20 bucks a quart and you can use a touch up gun. There is no thinner required with it, just stir it up, pour it in the gun and shoot it. TR

Here is a very good reference for bodywork/paint. This is put out by Southern Polyurethanes which makes very good primers and clear coats.
