I sanded my top dash down today, man that bodyman put alot of primer on it. and I just applied some plastic promoter (Bull Dog Spray) and after it dried it had cracked in a few places. Before appling I cleaned the dash with paint thinner, then with soap & water, and then I dried it off everytime I used a different towel. What can I do about the cracks, just sand it back down or apply filler primer around the cracks and wetsand it?

did you go heavy on the promoter? is ALL the texture gone? is the primer cracked a little under the promoter? and how humid is the air when you sprayed it.

there isn't any primer on the plastic at all I have sanded it all down. There isn't any texture I can see, but there is probally a little there in a few places which is why I put a few coats of filler primer on after the promoter then wetsand them(but I haven't done that step yet) It was pretty normal outside, not too humid at all. And I applied just as specified and didn't put it on heavy at all. How much should I put on there anyway? After I'm done with the promoter should the entire thing be coated in the promoter or just misted with it?

That promotor stuff acts funny on some surfaces. On my lower dash i sanded it smooth, but it wrinkled up in a few places causing me to have to resand everything and do everything twice. I just misted the promotor on, just two lights coats before i went with the paint. The lower dash is the only time i've had problems with it, every other time it went on great and helped keep the paint from running and not wanting to stick.

I heard of people having problems with the Bull Dog as you said. I have never used it.


I wouldn't us paint thinner, then soap and water to clean the part before you spray it though. I would use a wax and grease remover "kind you get at paint supply stores" then spary it.
