ANAC 10P4-2

During fall, in 2006, I primed and left some test pieces outside. I live in Florida and I'm less than 1/2 from the beach so the pieces got their fair share of humidity, sun and salt air which should have promoted corrosion. I'm happy to report all the test pieces are corrosion free. In contrast, I've recently found some corrosion after pulling the blue plastic off some of my parts.
Test 1: No preparation; primer held but can be removed with light scratching and flakes off. Further bending will continue flaking process.
Test 2: Light wipe with acetone; primer held by can be removed with scratching. Will sometime flake but I suspect this is due to a poor "cleaning" on my part as it rarely happens and then only on the small odd spot.
Test 3: Scrubbed with Scotchbrite pad, wiped with acetone; primer held and won't be removed with scratching unless it's a deep scratch. Bending (within reasons), dimpling and other activities do not appear to be a problem now that the has set. Having worked with the primer, before the paint as set those activities could be problematic.
Test 4: Scrubbed with Scotchbrite pad while cleaning with soap, wiped with acetone. Same results as test 3.
