wet /hydroblaster info needed

Hi folks I have had a great time conversing with some of you the information you give me is great and I thank you. So with that said here I go again I have a 1987 Smith 100 air compressor which has a ford 302 motor which uses 4 cyl. to run and 4 cyls to produce air it is capable of going over 200psig at 80 cfm but I generally run it at 100psig at 100cfm which in all the things that I have needed it for it has been great. I have a harbor freight blast pot about the size of a 30 gal propane tank I am looking to build a wet blaster for my cars to clean the rust and old paint off the cars, I also have a power washer that is 3300 psi I am looking to build a wet blaster I can get the kit from northern tools I am looking for feedback on any aspect of doing this pro/con triumphs and failures in short I would like to know what I am getting myself into. thank you in advance.
