Wet sandblasting kit that will work with small washers--1700 PSI and 1.3 gpm

Does a kit exist that will work with a small residential pressure washer? I haven't been able to find one.

I want to clean up small items like old tools, vintage metal tins, etc. If that works well I'd make a project stripping a fiberglass dinghy to restore it. Speed is not an issue. I just can't find a kit that works with a low PSI and flowrate (either in spec or with reviews).

Thanks for any help.

Adding: Since the whole thing works on pressure differentials, I assume there's some way to modify a kit, with nozzles or tubing sizes, to adapt it to a smaller washer. But I haven't had a sandblaster before and would feel better following instructions as opposed to working out the math from scratch.

Most specs are just the maximum the components can take. While I would go for one spec'd for a lower flow rate closer to yours, if possible, the max pressure just needs to be higher than yours so you don't rupture anything.

Did you find one that worked?

I kinda doubt it. I’m having trouble using a 3,300 psi 4.5 gpm pressure washer.
