Leeky1 Posted September 6, 2010 Share Posted September 6, 2010 Went down to the local paint/panel supply shop otherday and noticed a small Sand blasing gun for $35. I'm getting my car Garnet blasted soon as I feel that's the best way to clear out most the rot but for the smaller panels etc that I've already pulled off I thought I might get away with buying one of these and doing it at home. Any had much experience with these and is there anything I need to be aware of? I'm trying to restore my car a cheaply as possible while still doing a thorough job.

Simon Posted September 6, 2010 Share Posted September 6, 2010 Hope you didn't buy it. They are 100% useless. Used one last week and I actually lol'd at how crap it was. Even at 160psi. Quote Link to comment Share on other sites More sharing options...
Leeky1 Posted September 6, 2010 Author Share Posted September 6, 2010 Na I didn't buy it. That sucks, was hoping this would be a cheap way to clean up all my rusty bits. Which is almost everything not plastic or glass So what do you recommend? Just bite the bullet and find someone to blast all the parts cheaply?

Simon Posted September 6, 2010 Share Posted September 6, 2010 It depends how bad the rust is and how hard it is to get to. If the rust is easily accessible with a grinder and rust kill spray be it panels or under body parts I would just grind it all out / off. If the majority or the rust is in hard to get to places then I would probably just get them to media blast those places. There is no point in getting it blasted is any of the rust spots are going to need patches welded in. You can get great results with a bit of time and a grinder. The important bit is to get paint over the freshly ground metal or you get back to square one. Quote Link to comment Share on other sites More sharing options...

RUNAMUCK Posted September 7, 2010 Share Posted September 7, 2010 I found we had to dry the fuck out of the sand to stop it from clotting up, and sift the buggery out of it to. Then it worked fine. BUT they consume a shitload of air, and fill your hair/pockets/shoes with sand. plus I had to wear a welding helmet cos my face was getting cained with sand. (Fucked the lens too.) I just give a mate a box of tui and he does it for me. win. Quote Link to comment Share on other sites More sharing options...

Truenotch Posted September 7, 2010 Share Posted September 7, 2010 20kg for $20 at the toolshed in Fine, Medium and Coarse grades. Quote Link to comment Share on other sites More sharing options...
bubblegoose Posted September 7, 2010 Share Posted September 7, 2010 beach sand, silicosis? thought that was only from glass? hmm oh well Quote Link to comment Share on other sites More sharing options...
Truenotch Posted September 7, 2010 Share Posted September 7, 2010 Yeah, beach sand = silica = silicosis. It smashes up into tiny particles that get stuck in your lungs... I've only seen the gun that Simon is talking about... It was crap, but I'm sure there must be better ones around. Quote Link to comment Share on other sites More sharing options...

I thought I'd get a cheap gun, go grab some sand from the sea(although that shit that come up in the earthquake looks really fine) throw on some sunnies and a paper breathing mask and go nuts in the driveway!

Coldspark Posted September 8, 2010 Share Posted September 8, 2010 How do you keep the dust down in that drum down? I made a box just with wood and a piece of glass but after 2min of sanding you cant see shit Quote Link to comment Share on other sites More sharing options...
