What kind of Paint and Aluminum tubing should I use in my boat conversion?

[Jim Bridger]

I'm converting my 14ft v-hull into a bass boat of sorts...just adding a casting deck up front and a deck lower down in the rear.  I'm a fairly big guy weighing in at around 275lbs and I'm usually pretty hard on my equipment, I don't want to use wood 2x4's as support and framing for this decking.  I'm planning on using aluminum square tubing, however, I need to know what the minimum size square tubing I need to use that will still support my weight.  If anyone knows the answer to what size aluminum tubing would replace a 2x4 whilst matching support strength, please let me know. 

 

Also, I'm wanting to repaint the boat and make it purty...what brand of paint and primer ought I to use?

 

Lastly, what would be the recommended as the best method for attaching the framing to the hull and the decking to the framing?

 

Thank you for any and all the advice yall give.
