Great adhesion

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.

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.

Great for vinyl windows
I used this on a vinyl window frame before painting it. I have tan vinyl windows in my house and white interior trim. It did not look so good and I wanted to paint the interior part of the windows white. I used this to prime the window after sanding the frames before painting them with white spray paint. This really improved the adhesion of the spray paint. The paint has held well for many years. I have also used this to prep plastic bumpers before painting and it works well for that also.
