The other thing you'll see is the compressor off times will be longer and the compressor on times will be longer. Which will give you fewer starts. I've always thought the fewer starts and stops the better. Sounds less expensive than buying another compressor.
Mostly what soaks into the steel is the mercaptan odorant. You might get some rotten egg smell for a while. People who make smokers out of propane tanks burn them to get rid of the odor.
If I did the calculations correctly a 500 gal tank holds about 682 cu ft at 150 PSI. If your Blaster uses 20 CFM it would take about 6 min to lower the pressure to 125 PSI, 12 min to lower it to 100 PSI.
