I'm wanting to take my frame down to the bare bone, but dont want to take the time to sand. My Q. is that if I hydroblast the frame( thats with water) will that mess it up or will I have problems when I go and paint it.I blast for a liveing and have seen stuff come off surfaces that I thought was there forever. Im thinking that 10K-15k PSI with a spinner tip will do the job. THANKS for all the advise!! GO GREEN!!!!!!
