Skvitt Posted August 23, 2021 Share Posted August 23, 2021 Sharing my experience. After reading mixed reviews, for $35 worth of hardware I decided to try it myself. Here it goes. In a few words - it works. Ran out of glass media very fast though. Link to comment Share on other sites More sharing options...

Skvitt Posted August 23, 2021 Author Share Posted August 23, 2021 Trial notes: -in general it works -I wouldn't say it is less messy than conventional sand blasting, no dust alright, but sand is still flying all over -all sand delivery parts MUST be absolutely dry. -media MUST be absolutely dry, I had to spread that playsand on my driveway in direct sunlight to dry it -uses a lot of media, need to figure out how to collect and recycle it. -good thing I did it on a hot sunny day, so I could use garden hose to rinse myself had to toes. (wearing swimming pants helps 😊) -It leaves a small amount of surface rust as it dries out, which should be perfect for POR15. Or Evaporust to the rescue. -I won't do small parts, but definitely will consider  for frame blasting.         2 2 Link to comment Share on other sites More sharing options...
m-mman Posted August 23, 2021 Share Posted August 23, 2021 Quick re-rusting and need to recycle media seems similar to my experiences with dry blasting. Decreased dust can only be a benefit. I think that whatever you do it is going to be a dirty ugly job.  I have a cabinet that I use all the time for smaller items. It solves many of the inherent issues (dust and recycling and keeping the media dry)  Link to comment Share on other sites More sharing options...
39BuickEight Posted August 23, 2021 Share Posted August 23, 2021 I always put large tarps under and around my work area about 10-15 ft out and swept up and reused the media that way. I could reuse it 3-4 times usually before it became too contaminated that it wasn't worth fighting to get through the nozzle. 1 Link to comment Share on other sites More sharing options...
jpage Posted August 24, 2021 Share Posted August 24, 2021 The real pros treat their water supply with a rust inhibitor to prevent flash rusting. I think, conventional blasting works just as well and is usually less money! 2 Link to comment Share on other sites More sharing options...
Skvitt Posted August 24, 2021 Author Share Posted August 24, 2021 My problem with conventional blasting is the air supply. 1 Link to comment Share on other sites More sharing options...
trini Posted August 24, 2021 Share Posted August 24, 2021 My observation with media blasting is there are still tiny pockets of rust left over, depends on the depth of rust. Try this experiment. After sandblasting wash subject clean with water and then wash with some muriatic acid. The acid will then remove the rust in the tiny pockets. It is possible to do the same with vaporust which is safe. The downside with sandblasting is the lost of metal not to mention making a small hole larger. After using any method to remove heavy rust it makes sense to rinse with vaporrust. Ever tried lemon juice ? Link to comment Share on other sites More sharing options...
Restorer32 Posted August 25, 2021 Share Posted August 25, 2021 We used to sandblast outside 48 hrs /week so In think I know a bit about blasting.  Sandblasting does not remove metal. We have been using a blasting booth in the shop at least 8 hrs/week for 40 plus years and have seen no metal removed from the walls of the cabinet. If blasting makes a small hole larger it is because the hole was rusted. We have sandblasted about everything you can imagine including Duesenberg sheet metal without removing metal. Warpage is the enemy, not metal removal. 7 Link to comment Share on other sites More sharing options...
chistech Posted August 28, 2021 Share Posted August 28, 2021 That is the benefit of the dustless blasting technique, there is no warpage because the water keeps the surface temperature down. Straight sandblasting with just a pressurized system creates a lot of surface temperature from the friction of the sand striking the metal surface. My entire 32’ Olds body was dustless blasted and was straight as a pin when done, even on the large flat areas. 2 Link to comment Share on other sites More sharing options...
Borough Essex Posted September 5, 2021 Share Posted September 5, 2021 What did your granddaughter say about the missing sand?:) In return you had better promise she can use it on her wedding day after you have restored it. 1 Link to comment Share on other sites More sharing options...
Restorer32 Posted September 5, 2021 Share Posted September 5, 2021 Actually it is not the heat that can potentially warp sheet metal when sand blasting. It is the peening effect of the sand grains hitting the metal. 1 Link to comment Share on other sites More sharing options...
airoshotblast Posted April 6, 2022 Share Posted April 6, 2022 I think use of wet sand blasting machine was a wise decision Been a enviormentalist I always prefer that industry and industrial machines should co-op with nature for a sustainable development Link to comment Share on other sites More sharing options...
