ACRYLICS have enhanced weather ability, are very smooth, and it’s resins are mostly found in clear powder coatings. Acrylics also have great Filiform corrosion resistance. Filiform is a type of corrosion that occurs on aluminum wheels. Acrylic powder coatings are also the clearest and best coating on the market for clear coating wheels. These powders can be hard to get long term adhesion because they are difficult to spray. You must be careful with acrylics being in or around your other powder types because they can contaminate them. Acrylics are the most expensive resin type and aren’t the easiest powder to apply, however once you get the application process down, your finish is superb.
