Too late....once it's done, it's done and there's no going back
By the way, my last 80 gallon compressor air tank wound up with square top and front square doors... If you don't get a tank, don't fret....I will not go out of my way for tanks any more. If it falls in my lap, great. If not....go square...look up A thread titled .. " Mack ".
Make no mistake, there ain't no powder in this Puff ! And... I'm not really a crazy person but I play one in real life
