Never had a pressure washer strong enough at the time to run my wet blaster when I was working on the bottom. Mainly used it on engine compartment due to all the tight spaces I couldn't have gotten to otherwise. I had never used one before and was amazed with the results. Mind you next time it will be done entirely outside due to the mass amount of sand and water. Only downside of it was the flash rust as soon as it started drying, even after being blown off with compressed air and wiped (due to high humidity of blasting process). Cleaned off super easy though.
