WET SANDBLASTING A 914 Options

[Curbandgutter]

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 would use a rust converter especially if the color of the metal is still dark, but with a sponge to keep it out of the seams. Avoid any runs or sags and watch for little parts of the sponge hanging on the rough metal when you start painting. I spent about 4 months on a 42 ford jeep and it had so much converter on it we reblasted it and then I rewiped it with a thin coat of converter and primered it before I started wiping filler on it. The driver side and floor was pretty far gone. Epoxy non sanding primer then seam sealer then when it is ready another coat of epoxy non sanding primer thinned with the same brand single stage reducer ie: dt reducer to keep the orange peel down. Then I apply the sanding primer. I try to spread filler on the non sanding primer pretty quick like it was a coat of paint otherwise the primer will need to be roughed up and then you gotta watch for scratching through the primer. I use a lot of epoxy non sanding primer to avoid all the extra sanding. You can put the mixed paint in the refrigerator and even the cup off the gun If you gotta stop for awhile. You will need to watch the gun head and blow wash thinner through it if it has to set very long. I would also try not to blow the blasting material into cavities. Hope it turns out like you want it to.

Once a contractor asked me how did I like the job he did on my driveway and I said nothing turns out like I imagined it but it was ok.
