Let me start my post with a confession - I learned only after I received the SPI epoxy primer that I am supposed to use the SPI Wax & Grease Removers. Since I was in a hurry, I used Klean-Strip Prep-All, to clean the parts.
The first batch I sprayed turned out just fine:
Today, I sprayed a second batch, what turned out to be a complete fail:
I am now wondering, if using the wrong cleaner is my only problem (I will order SPI cleaner tomorrow morning) or if I have something else going on?
The only two differences, I can think off compared to the first batch, are aluminum instead of steel as material, and that I removed some markings with MEK, prior to cleaning with Prep-All, 80 grit sanding and cleaning with Prep-All again.
Three steel parts, which I had media blasted, instead of sanded, showed similar defects.
Any ideas?
