Hi Mathazar,
I'm not far beyond newbie myself but I just finished a snake condo (four condo snake cage) with Varathane polyurethane top coat applied with a very cheap (think I paid like $10 after a 20% coupon) Harbor Freight paint gun and was extremely impressed with the results. Just watch a few YouTube videos and you'll be up to speed. I will be watching your progress with great interest as I'm contemplating doing the same to my Mata Hari!
