Hmm, I wonder what ospho will do to dynatron-550. My problem is that the patch I riveted has something like 60 rivets holding it on now so I need to etch it in place before repainting. The rivets were all "wet" using dynatron-550. Would ospho eat away at that stuff and ruin the seal?
I wondered the same thing. So I tried it.
IPhone does not appear to have any effect on the Dynatron 550.
