I have used it in the paint shop since its first introduction in the shops 6-7 years ago .
Its a great product and I also have my body men using it over their last skim coat of body plastic to make sure its straight .
The product goes along ways too .
And it will not contaminate your primer if sprayed over , like in pin holes small imperfections , or if you have a bad low area and needs a skim coat of Polyester Puddy for getting the panel straight .
