I too use clear for the protection and not the gloss. I actually prefer matte and satin a lot more.i used that plastic paint from Wally-world (walmart) and it has chipped like a son b***h. with the dupli color adherer it works well as a primer, with all other primers i had a problem with flaking chipping and overall uneveness. but i alo didnt clear it well. i have been looking into clear coats more as a protector more than a "shiny finish"... but thanks for the help
