I was wondering if anyone has had personal experience applying GBP-988 spray can primer over Al treated with alodine?
SW tech support says not recommended. however, someone from a local paint store says he has personally had no issues with using a SEM primer over alodine.
I was initially only planning on using the 988 for priming. however, on some VS ribs, I overdid it with the scotchbrite and wore through the alcad layer in spots. Next time, i won't bother trying to debur every tight spot; however, I did learn how thin the alcad layer is.
At one end of the spectrum, instead of leaving these spots, i thought I might try to alodine treat these spots where i wore thru the alcad (maybe using the alodine pen?).
At the other end of the spectrum, i thought why not just alodine treat an entire part, so the alodine treats all those scratches and machined areas. From what I have read, alodine is not very effective on untouched alcad, anyway. This way, every surface area has the outer primer protection as well as an inner alcad or alodine protection layer as well, even at machined edges and holes.
Thanks for the input,
Jae
