I'm hoping for some insight here, not a sales pitch. In my opinion, both of these fillers fall under the "Trick of the week" category. This category is filled with body shop goodies, self-etching primer and sprayable polyester filler come to mind.

So, someone tell me when these fillers should be used... AND why? I seriously want to learn something here, please be ready to back-up your opinion, that's why I'm asking the question. Several sales people have tried over the years... in general, they are weakly prepared to answer questions with facts, yet full of useless sales lines.

Thanks, Paul
