Decided I would Por-15 the insides of my hood and fenders. Ground all of the old undercoat, paint and rust with 60 grit sanding disc to make a clean, rough surface for the POR-15 to grab on to. Any spots I couldn't reach with the sander I used my small media blaster to clean and roughen the surface. Used marine clean washed off with water and blew dry with air gun, then sprayed on metal ready and let sit for 30 minutes, washed with water again and blew dry. Let parts sit for a day to ensure all water had evaporated.
When I applied the POR-15 tonite it appears to have lots of tiny bubbles, as if there is dust under the paint. It is not fish-eye as it is too small and I made sure there was no blasting media on any of the surfaces so it is not dust - it definately looks like tiny bubbles.
Any thoughts on what went wrong? Any ideas on how to fix it? Should I see if I can sand out the bubbles and apply a second coat? Not sure if the second coat will be any better. I am thinking if I have little air bubbles everywhere I am not getting the maximum protection I would expect from POR-15.
