So I asked this question on previous version of this site, but I need to ask again. I want to paint the rims I use for auto-cross. They are 5th gen rims and they are the stock gray color. I know I have to clean and scuff/sand them before painting, but do I need a special primer since there are some areas where the finish is scratched off, down to the aluminum?
METAL-READYTM provides the best adhesion for POR-15® on any metal surface, including aluminum and shiny polished metal surfaces. Our simple process gently etches metal, creating an ideal anchor pattern for coatings such as POR-15®, while simultaneously leaving a zinc phosphate coating to insure chemical bonding of paint and steel. Avoid other preps that may leave harmful residues which prevent proper adhesion. After thoroughly degreasing your work piece, apply environmentally safe METAL-READYTM to both neutralize any rust and etch any clean bare metal. This will allow better adhesion of POR-15® or any other paint. METAL-READYTM is not caustic, corrosive, toxic or flammable. Do a search for POR-15 and any place that sells it will also sell metal ready
For mine I just cleaned them up real good, and used vht polyurethane wheel paint.... Has held up fine for me!
Thanks for the feedback guys! I'll try just using the wheel paint first as that seems like the least exspenive solution. I'll try the METAL-READYTM is the wheel paint doesn't work.
