Need some advice with prepping and painting aluminium. Not a Z body panel, but is to be installed on my Z.
So far all I've done is give them a decent sanding, but the aly has a few deeper scratches. Tried doing some research online, but kinda got lost. Do I need to fill these or can I just use a primer? And then what sorta primer would I want (filler, etch, urethane, epoxy)?
Can anyone with aly experience / knowledge explain the process and recommend some products (including paint etc)?
Cheers
