### ⭐⭐⭐⭐⭐ Beautiful results, quality products!
*by T***I on August 20, 2018*

We purchased all the spray products, from the adhesion promoter, primer, color coat, and clear coat satin finish. In addition to following the can direction, we also followed some very specific technique directions we found on the internet, about painting plastic dashboards (which was the project). Basically, follow all can directions, GENTLY and LIGHTLY WET sand the surfaces with 800 grit, dry, and clean well with alcohol before starting. Start with adhesion promoter, follow can instruction. Then spray primer, color, and clear coat in 2 - 3 very light coats, each, and when you finish all primer coats, wait 24 hours to start color coats, and do the same when color coats are done, and you are ready to clear coat the piece(s). We allowed all of that to dry for 48 hours, before reinstalling. It looks wonderful. Not like we just spray painted a dash. It's a hard finish, and no chips or scratches when it was re-installed in the vehicle. Compared to spray paint, it's a little pricey, but it was well worth every penny.
