Hey
Here is my experiance sand balsting - it all depends on what you are
blasting. If you are trying to blast paint - good luck I have found that
it is easier to use a wire brush of a stripping solvent of some sort. If
you are trying to get of surface rust (like on a frame) then blasting is
great I was able to get to shinny metal in no time - I did have to sand it
with a fine grit sandpaper to make it smooth. If you are trying to blast
undercoating or anything like that - you'll have more luck with paint.
Now I use a standard home compressor (your sounds simular) but I wasnt
haveing a lot a luck with the syphon blaster - so I went to a pressurized
deal (the sand is in a tank the gets pressurized) this works great for
small to mid sized parts - for large parts you will possibly want to get
one of those compressors that you pull on a trailor and a hose the size
fireman carrry - my neighbor blasted and entire frame and several body
parts in a couple hours - with that system you have to worry about heat
damage.
As far as sand goes - I use a black sand - dont remember off hand the
brand, but I can use it for a while before having to replace - just
remember NEVER use silicon - it is bad for your lungs - can give you
cancer or something dumb like that.
Well I doubt that helped any but - who knows. Sorry about the ol'
spelling and grammer - in a rush.
