I purchased a 10 gallon compressor. I think I will Use Raptor Upol. It might be a bit my body isn't happy about all the work I have done. Also thinking about getting a sand blaster if the prep is too difficult. Does anyone know how well a soda blaster would work? Seems like it wold be safer for lungs and cleanup. It does cost more. HF also has a gun with a 20 oz hopper for $20 You just plug in the air line and pull the trigger.
