does anyone here do tank modifications?

mig is easy to use for most welders and is fine most people use 16ga steel for tanks .If your a tig guy you should think in terms of aluminum tanks as they are the coolest.check out the uk company called the tank shop .Go to barnes and noble or any large retail book store ask for the transportation section, you will find some great books on metal working and panel beating and custom bike sheet metal work,even how to chop japanese bikes how to books plus custom painting books .they are mostly picture books with informative how tos and tech answers you should have at lease one copy of such a book as reference by your shop bench .they answer plenty of fabrication answers in the text or via a how to pic.
Im surprized most people never venture to a book store before they start any project you get first hand pro advice ,from pros with years and years of hands on expert advise they have made all the mistakes they have tried all the materials and have worked out methods that have proven success.then they sell you all these years of expertise you can tap into their heads for twenty dollars.
Speaking of paint cans,you can do hi qaulity finnishes with spray cans "rattle Cans" for or uk counter parts.It just takes alot more coats with a spray can and you should stick with the same brand or text mixed brands.I was reading one of my guitar mags either guitar one or guitar player and in the back there was a book for sale called custom guitar painting using nothing but spray cans.See thats the kind of book I would get if I was even thinking of doing a project with spray cans.Reading before you start a project gives you expert advise right from the horses mouth .

Im so far behind ,that I think Im in first.
