Anything Wrong With My Frame Painting Method?

I used 5 bags (300lbs) to do the whole car..inside, outside and underside…I sandblasting in a portable garage with poly on the floor so i can recover the media and reuse. The poly is Stegawrap Tm. It’s puncture resistant poly that is gererally used for pouring concrete over floors.. FYI its not UV resistant

 

Im sure 750 lbs is enough..lay a tarp down to recover media for reuse if you have any doubts.
A 3M 7502 mask is cheap and most comfortable, use dust filters….certainly better than a disposable mask

 

The amount you use will vary drastically with the amount of rust. Paint and light rust comes off easily heavy rust takes more time and sand

 

Im using a 18 CFM @ 90psi compressor. It can keep my small HF pressure pot going constantly. Years ago i had a 7cfm at 90psi,,there were many pauses waiting on pressure to build,,so doublet the time to get the job done….many pauses turned into beer breaks..

 

You have much more patience than me lol
I get grouchy about having to refill the pot every 20-30 minutes
