Im only giving one comment, to my knowledge there is not 1 single major manufacture using Do It plastic. It is a retail market. That said when you only get about a 1% discount on a barrel. Its a no brainer to see why there isnt. That said, its good stuff. As there are plenty of other good ones as well. In the end its all opinion. I can get our plastic well over 400, and its still very durable. Some day i will do a side x side comparison with a few other manufactures for real data and to prove and disprove some theories.
