When I did my motorcycle tank I sealed it up with tank cleaner and 1/4" bolts and nuts. Then I put it inside heavy duty plastic, packing taped that up, then wrapped it all up in a ball of blankets, taped that up then put it in the clothes dryer on no-heat for about 2 hours. It was sort of noisy but not too bad, no dents, no dryer damage. Not sure Kevin can do this with his tank though. Maybe the laundr-o-mat lol
Haha thats a pretty inventive idea I wouldn't have thought of that lol my homemade tumbler worked pretty good. Its clean enough for me I let it soak in some pine sole. And I'm gonna wash it out with dawn. Good to go!
