I’ve never used a spray gun, but I’m wondering if it’s time to bite the bullet & give it a go. I throw this out there because I’m needing a fresh coat of paint on my custom made steel gas tank before I install it in my 37 Coupe. The inside of the tank was done a couple years ago & after modifying a tank sending unit to work it’s time to get this sucker painted & installed. I was going to just spot paint it with a rattle can but after some self etch rattle can primer, I’m thinking twice about the durability of a rattle can paint job on the gas tank which will likely take some abuse under the car. I have a pint of POR15 which I could use if I grabbed a cheap harbor freight spray gun, so what can you suggest? Sent from my iPhone using H.A.M.B.
