Dont Do It (voice of experience here)
I did it and it was really expensive for what I did, Cutting tapes, Many cans of Primer, and Many many cans of Krylon
I was in for $140ish 4 years later it is rust city.
I could have used that money on a good Epoxy Primer, and HVLP gun then thrown another 150-200 I'm guessing and had something good., Plus the Gun.
