Okay, I have a new aluminum water pump that I would like to paint chevy orange. What are the prep steps to paint the pump? Do I use rough up the surface then use a solvent to clean it or is there a special prep to use on aluminum? The guy at Jegs said not to use solvents on aluminum but soapy water instead but the paint guy at the body shop store said to use a good degreaser after sanding such as PPG's DX330. Who is right?

Thanks in advance for your input.

If it's new and not polished, I would just clean it with some thinner, let it dry and spray it. That's all that should be needed.

I agree with Mike.

I would add that I masked off the shaft and weep holes before I sprayed mine. A few minutes spent masking these areas will ensure that it turns out real nice for you. Nothing worse than a mad spray bomb artist...
