I posted a couple pics of the frame after the phosphoric acid. The instructions on the "Metal Prep" from Jim Carter said "keep wet 10-20 minutes then rinse thoroughly". I followed the directions, rinsed, then blew dry with compressed air then heat gun to get all the moisture out.

The frame appear splotchy, although I'm not sure how metal is supposed to look after the metal prep. I used the prep since most of the metal had no rust whatsoever and was perfectly smooth after wire-brushing to remove the original paint and primer. The frame will be coated with POR-15.

Is this how it is supposed to look? Can you overdo the acid? Anything else I should do prior to application of the POR-15?
