It won't work particularly well, especially if your compressor has a small tank.

You'll be able to do short amounts of work while you wait for the tank to recharge. If you're just cleaning small parts it will work fine.....
Depends on the blast cabinet and gun, likely the compressor will run continuously in most cases.
Even the HF a portable blaster says 6 CFM @ 60 PSI; 25 CFM @ 125 PSI
Pressure tank vs gravity feed ?……… Air Consumption: 6-25 CFM,
Lower CFM is going to slow………..car frame is going to take a while.

The pressure washer sand blasters are very temperamental……….some report OK results by making the “sand” a slurry mix. They can be slow and messy…….but all blasting has a mess, dirt and dust factor.

Syphon sand through pressure washer. 8 CFM is not enough for sandblasting
I run 18 CFM at 90 no issue but the pump is running very frequently

To sand blast, you'll have a little "duty cycle", but that's okay.

I should've stated my setup above: 13.5 CFM @ 90 PSI, 60 gallon tank, and a large roll-around pressure pot sandblaster. The compressor runs continuously when blasting, but it keeps up.

As long as they are both rated for the same psi you could have as many compressors as you could power up tied into the same line. If both were 8.5 CFM then you would be delivering 17 CFM
It's preferable to set the pressure switch on them slightly different so they don't both kick in at the same time, say one of them 125-95psi and the other 120-90psi but that's easy enough to adjust

The biggest problem with any sand blaster is that the nozzles wear out. Find out what the replacement nozzles cost.
And they use a lot more air with just a little bit of wear.

The standard nozzles that came with my TP Tool cabinet were steel and wore quickly. I was talked into the ceramic nozzle .....a BIG difference. A ceramic will out last a dozen steel nozz.

Try a boron nozzle next they will outlast ceramic nozzles by a long shot
I bought the one called sandblast kit with 10 ceramic nozzles for 80.00 free ship. It works with a pressure washer plus I bought a gravity fed gun. But its 90 deg so I'm putting up (4) 2 in dia x 10 ft long pieces of conduit in (4) 5 gal buckets with a 2 1/2 dia pvc pipe in the middle with rocks around the pvc pipe. Then attach a 12 x 12 tarp using u clamps
