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'm old school BUT for a full strip "dustless blasting" is the new kid on the block
Its wicked fast, uses about 80% less media versus straight media blasting. The wet plasma helps everything along and flushes the debris away. Correct is does not generate heat, in fact it gets cooler a couple degrees below ambient which eliminates any fear of warping. I've seen glass beads used as media. Water will get everywhere so making sure the H20 has a place to exit is a must. Warm weather would be an advantage. The bare metal finish is interesting since the water buffers the media impact and you don't get a gigagazillion micro craters. I saw this demo'd on truck body parts both on aluminum and steel. On aluminum I would use it in a heart beat. I would do it on steel but I would still machine sand AND use a lite chemical metal prep. You can also learn from Andy the resident German that in some places duct tape may help sealing off areas you do not want media to get into. In the end you are going to have media in places including your ears that you thought it wouldn't get into. |
