I have my chassis complete and rolling... now working on the body panels... Took them out of storage... bare metal panels had some light surface rust on them so I sprayed them with POR 15 Metal Prep. Kept it wet like the instructions said... all the rust had dissolved after 30 minutes so I rinsed it off...
Well after I rinsed it off, the rust on the surface was WAY WORSE... See below for before and after pictures... and yes the pictures are named correctly.
What did I do wrong? The whole goal was to eliminate the sanding... now looks like I will be working out the ole manual sander...
Any advise?
