Works as stated.
I painted a couple filler panels between tank and fairings on my Honda motorcycle. I used this as it was recommended by SEM, also the maker of the top coat I had chosen. It goes on thin so no real buildup in thickness of the paint which is desirable. If you follow directions it will not run. I top coated using multiple light coats and the result is a professional looking paint job. These products are not cheap but sometimes you have to do it right when painting a high value project. I would recommend this product to anyone.

Performed amazingly.
Did its job helping me epoxy and patch a hole in a plastic bumper on a 2020 Traverse. I've done similar jobs without using this and I can say the adhesion time was noticeably quicker and cured out stronger as far as I can tell.
