Zephyr, yes I agree 40 should be an adequate blow out after a good soak, but when I am trying to air up my 50-60 lb tire pressure on my truck and such, it can be a challenge at 40 lbs or less. Lots o waitin’ if it ever even does get there.
Kerry, hmm never thought about going used maybe on a little bigger compressor if I can find one, but like you said, to check it out good or possibly inherit someone elses probs.
