That's not the only concern. It's the oil in the air compressor that's the concern....i really don't see the plastic being a issue.
As we talked about in our pms I would really feel better if someone takes responsiblily when doing the tank. not me being responsible. Stuff happens and I just want the bases to be covered. Not saying something would but to me that extra $ is worth spending..
You ever watch the fail videos... kinda like that u can do something hundreds of times only takes 1 fail. And on my tank I won't,can't risk it.
