Re: Removing Paint

I’ve had good outcomes with the self etching primers that I get from NAPA.

The biggest challenge is getting the parts really clean and grease free. Aluminum is porous and will absorb oils.
A good soaking in a parts washer followed by washing with hot water and dawn.
I then let it sit in the sun and warm up which helps bleed the oils out and wash it again.
Just before priming I will give it a light sanding with a fine scotchbrite and wipe with Acetone.

I’ve had good luck with the rattle can self etch primers.
