I bought this kit to turn my power washer into a sand blaster and it worked really well! I sand blasted the front and rear bumpers off my Jeep Cherokee. Advertisement Link to Sand Blaster ebay.us/HGv2qe
If you were doing a large project It might be a better option to get sand from nursery/landscaping place it's like 55 to 75 for a yard. You would probably need to strain it and make sure it's dry. The 75 buck stuff we have in our area is very clean to start.
I didn’t have an issue when I filmed this but if you get a little water in the pickup tube it does clog up. You just have to make sure the sand is dry and the pickup tube is dry. Otherwise it works good.
