According to the instructions on POR 15, the first step is to clean the metal. Yes, I'm aware you sandblasted, but cleaning the metal will remove all oils and stuff from handling.

Second, you apply metal prep, which etches the metal properly for the POR 15 to bond to. Both of these steps are really helpful to get the proper bond to the metal. Then either spray or brush the POR 15 on. It self levels, and I've used both processes with good results.

I've never used topcoat on a frame. After 10 years, the frame still looks glossy black, although in defense mine does not sit outside. Topcoat will only add another layer of protection.

Lastly, one coat of POR 15 is enough. There is really no value to a second coat, especially if you are going to use topcoat.

Good Luck! I believe this to be an excellent product, superior to powder coat in many respects. I've enjoyed mine, and am likely going to paint the entire underside of the next project with this or KBS coatings Rust Stop!
