Denny, if you had only ask

I have a gravity feed blaster that I purchased from Eastwood in 2005 and have never used it....never! My neighbor used it to blast one car fender and I did not watch him do it. I would suspect how well it works depends on the nozzle size and pressure.
I may end up selling my gravity AND my pressurized blaster. If it doesn't fit in the blasting cabinet it goes somewhere else!
I"m done blasting guys. To old, to nasty and to hot plus you can spend some money in buying the sand/media.
