How well does this primer adhere to aluminum?

Answer
Seymour Paint –
If the aluminum is old it will probably stick fine, but we do make a self-etch primer that is specific for this metal (#20-1681).

Should i use big rig heavy duty primer or your self etching primer on a bare steel farm truck steel bumper? The bumper will see a lot of abrasion with straps, chains etc. and I plan to paint with big rig gloss black after a primer. Please let me know what you guys suggest for primer and or paint for this.

JJFranco –
I have some running board brackets that are partially rusted (areas of rust and areas of bare metal since I had everything sandblasted). Will this product harm the bare metal without rust?? What black matte paint can I use over it?
Upvote if this was helpful (0) Downvote if this was not helpful (0) Flag for removal
Answer
Seymour Paint –
The rust converter will not harm the bare metal. Unfortunately, we do not have a black matte, but we have flat black.
Suggested Flat Black 620-1433
