Got the pressure washer sandblast attachment from Northern Tool. I bought 100# bag of mason sand but is has too much oversize material and kept clogging.
Screened the sand through a kitchen strainer and it worked much better but still not fine enough to prevent an occasional clog. Going to try some window screen next. Went through 50 lbs. of sand pretty fast.
Need to place a valve or maybe a smaller diameter hose to regulate the amount of sand since at times it flowed too fast. I did have the sand elevated and the hose attached at the bottom using gravity to help the flow. The blaster came with a long steel tube to stick into the media from the top and pull the media up into... maybe I'll try that first.
100# bag of mason sand was 6$
The Barracuda Rear Cargo Floor Panel
This took about 3$ of sand but I think I can slow the sand and still get good results. It flash rusts pretty fast but I didn't dry it or put any rust inhibitor on it either.
I set up on a tarp in the back yard and planned on letting the sand returning to the earth...
With some fine tuning I think it will be worth the $62 purchase.
