Hey mate its defiantly possible that tank doesn't look to hard, but in honesty that vinyl looks like absolute crap. Look for Avery conformable vinyl and stick it on dry, I just use my hands and thumb to scrape it out. Try graphic art mart they are our supplier, they are on the net ir just ring them and talk about what the application is for, from memory they will do public business to your door. Although postage is a killer with them its $25. But your best bet would be to get someone to do it as its not the easiest thing to do with no experience, if you choose to do it I could help you out as much as possible with advise but at the end of the day it all comes down to finishing it off like trimming it up. You would need prepsol, pointed stencil knife and heat gun. Some sign writers would charge a fortune so shop around and don't rule out paint to be the cheaper option you would still be looking at maybe $100 to get a decent bloke to do it. I got a local panel beater to spray my whole van satin black for $250, I did all the prep and its still schmick after about 5 years.
