ok well as far as the portable building goes thats out of the question. the 2x4 with plastic sounds alright. and also, im not trying to make this a showroom paintjob, just something thats going to look alright. i can probably get a garage to work in but i think it would be kind of a pain to drive somewhere to work on it, but i mean i guess that just a trade off. anyway, thanks for the advice.
