Front grille repair

67Dart440GT , I didnt say what I said for anybody to take offense. Was not my intention. However, I probably was not specific enough. Must be the fact that I am using 2 different aircraft type fepoxy primers made by Akzo Noble 512X310 is an impact resistant and fluid resistant epoxy primer and 10P42NF which is a fluid resistant epoxy primer. Basically impervious to Skydrol 7000 synthetic hydro fluid. I use these primers on framerails, inside framerails and under sides of floorpans or in corrosion prone areas. These primers react funny with lacquer thinner. Makes it crumbly looking. Not sure if you have ever used these products or you use something else. I also use Kirker Duraprime on exterior sheetmetal, door jambs, engine compartments etc. and also clean out the gun after use with this product with lacquer thinner. The Kirker cleans out ok and doesnt react funny, but not the Akzo Noble product. Next time I clean out my gun after using the Akzo Noble, I will put some of it in a cup with lacquer thinner, stir it up, and will show you pix of the crumbly looking crap that this epoxy turns into.
