Fisheye in por15 after using their metal prep

[Holtzer1]

Any idea why this would happen? I'm treating some pitted areas. I'm getting fisheye in the por15. I used their metal prep solution....not sure what's going on. Part was stripped with electrolysis.

Oil on metal or alkali from electrolysis process Por 15 is a moisture cure product.

Oil or silicone would be my guess. Did you use their cleaner/degreaser before the metal prep? I usually use some lacquer thinner, acetone, or prep-sol before the cleaner to eliminate fisheye.

applying anything too wet or too thick will also cause fisheye

Metalprep is for removing or converting corrosion. It has no solvent properties to remove oil, grease, etc.. Before painting anything you should clean things with an oil, wax and grease remover.
