Self Etching primer... Good or Bad?

I have been using the PPG DP Epoxy's for more than 25 years, with never a problem. It has stood the test of time over and over again on jobs that ran through my shop. Some epoxy products I wouldn't trust, personally. Just make sure if you are using a chemical stripper on panels to make sure it is thoroughly cleaned off before any top coat is put on or it will come up through on you later.
