Learned the hard way this past week. I had some minor pitting on the underside of my hood that I couldn't get clean so I thought I'd use Eastwood's Rust Enscapulator as a base coat and then seal it in with SPI's epoxy primer. I let the enscapulator cure for 48 hours and then sprayed the epoxy over. Couple days later I go back and stop doing some hammer an dolly work on some hail damage dings and found that the epoxy primer flaked off. I was even able to take a air hose with a blow gun and blow ALL of the epoxy off the areas where I used the enscapulator. Just came off in huge flakes.
I use SPI's epoxy paint and love it, but don't go spraying it over any kind of rust converter. I know on their website they specifically state to not use any kind of rust converters, but I guess I had it in my mind that the rust enscapulator paint was fine to paint over. I guess I also figured that since Eastwood states to topcoat it with their primer it would be fine. I was pretty bummed when I was realizing this but oh well. | | | | | Joined: Oct 2005 Posts: 4,261 "Hey! I sound like Darth Vader!! | | "Hey! I sound like Darth Vader!!

This was bugging me so I checked my can and it says to sand after 36 hrs.HTH
