    Aluminum Primer

     



    I'm getting ready to do a little project that involves covering new 1/8" sheet aluminum with spray-on 2 part urethane bed liner.

    The bed liner instructions recommend priming the aluminum before applying the liner. I contacted the company about primer recommendations however I haven't heard anything back.

    Does anybody have a recommendation on a good aluminum primer that is comparable with urethane?

    Look for a good self etching epoxy primer. Here's a nice, brief article; https://garage.eastwood.com/eastwood...imer-aluminum/

    It's much easier to promise someone a "free" ride on the wagon than to urge them to pull it.

    I know Raptor liner has an epoxy primer they recommend, I wouldn't think it would be different for aluminum.

    I use an etch primer on aluminum. Some of the epoxy primers are self etching, just something to think about when you pick a primer.
