Well I'm getting ready to wet sand blast (WSB) my project car and I wanted some input form those who have done it and or have some direct or indirect experience with it. I purchased a wet sand blasting kit from a company back east. I tried a sample piece and was thoroughly impressed. I was able to remove the paint down to bare metal on the underside floor in under 5 minutes. It was incredibly fast. The primer that I am using is an epoxy primer by SPI. I spoke with the manufacturer and they said to steer away from using a rust convertor as they can be very tricky to remove from seams. They also said to just blast it and spray it the next day. The flash rust will not be a problem. What has been your experience

I own the wet system. ( Dustless blasting ) I have used it on a couple different cars. The main problems are :
The sand PACKS into the corners and crevices. You will have to dig it out with a screwdrivers or something similar. In the time it takes to get the blasting done, rinse it off with the HOLDTITE and then clean out the crevices and rinse them, the flash rusting has already started. High humidity makes the whole system uselss as fas as the rust prevention goes. Here in Va where we get jungle like humidity, I have the panels starting to flash rust almost immediately, despite putting 2-3x the recommended amount of HOLDTITE in the mix, and the rinse Despite what Tom T says about sandblasting in general, this setup WILL NOT warp panels. I have tried. When I first unboxed it I held the nozzle 1" off the center of a 914 trunk lid for well over a minute and it did NOTHING to damage the metal It's a great system for the outsides, but IMHO it plain sucks in enough ways that I almost regret buying it |
