E-Coat on new fenders

I stripped it because of everybody recommending that you should strip it and after stripping and I asked myself why they waste my time stripping it when it was perfect. I bet that Taiwan boy probably works harder for his $.60 an hour then people here in the states working for $30 an hour. The next time I would not strip it.
I've bought and used over 35k in Amd sheet metal in the last three years.... I have sanded it and the ecoating rolls off of it in most cases.

Secondly, the texture of ecoating is rough, porus and has many imperfections, which means you'll need to sand it to remove all of the imperfections. Sand it, and watch how much is left. Ever check it with a mil gauge?
