Make sure you have proper ventilation, a paint mask or a respirator and some eye protection.
Even with proper ventilation, you may want to choose the time you spend in the paint booth wisely. There were a few points during the project even with my mask that I noticed I was light-headed.
You should also be aware that primers and paint will hang around in the air after they have been dispensed from the aerosol can. So keep your mask on even after you finished the spray.
Also, whatever isn’t covered in the paint booth will end up getting coated with a fine mist of paint. So, if you don’t want your junk like cell phones or cameras painted, don’t bring it into the booth.
I ended up using Rust-oleum’s self-etching primer. I don’t have a real good reason to use it.. other than believing all the marketing jargon all over the front of the can. I figured the anti-rusting compound would be good for a frame since it has to endure the elements. I don’t know if the self-etching crap works. I’d like to think sanding the frame surface helped along with that feature to set a good base primer. It’s important to note, I did lay down about 3 coats of primer. Just follow the instruction on the back of the can.
One note, if you do end up using the same primer as me; make sure to wet sand your final coat of primer once it dries. For whatever reason, the self-etching primer finishes with a slight popcorn finish. I actually tried to apply a test coat of paint in a small area of the frame and the popcorn is way to gritty. The final paint finish would have been bumpy and not smooth. So sand it down! I did a quick pass at the frame with a wet sand 100 grit paper.
