I do have a 60 gallon 12ish cfm tank so it's a possibility. Did you just buy a harbor freight one? I actually wouldnt be opposed to that if the open air (non cabinet) style blasters work well. I can do just about any small parts at work, we've got a 3 ft long cabinet but obviously cant stick a car in it. It'd be way more time effective to blast it, especially having a reasonable sized compressor already.
Do you have a link to the one you used? What media did you end up with? It takes awhile to get through the bondo on this thing.

The open air style blasters work quite well as long as you have a proper water separator and enough compressed air, but I guess that’s the case for any media blaster type.
I used the finest blast sand I could find, think it was 0,5mm - 1,2mm. 25kg/bag and I bought alot of them.
It eats through bondo pretty easy, I had alot on my car and it wasn’t a problem. As you probably know, you shouldn’t use sand on big straight surfaces as the roof, hood, trunk lid, quarter panels, front fenders, doors. Along the edges of big surfaces is okay if you are careful.
I don’t have a link to the one I used (borrowed), it was quite old, I’ve later also used my friends open air blasters, all from the cheaper end of the market, and they have worked just as good. One thing to consider is to buy one with the biggest tank that you can live with (have room for) as filling the tank takes some time, and you’ll do it alot if you’re going to blast a whole car.

Just before we laid the first epoxi base I got to borrow a ”real” sandblaster to create a good surface for the paint to attach to the metal on the underside of the car.
