I've just bought a 1995 16' x 6'2" modified V Mon Ark 1650MV jon boat with a steering console. Here is what I need to know:

-What kind of paint do I need for it (I want to paint the inside and motor and will be using a spray gun.)

-What's the best way to prep the surface w/o sanding off all of the paint, can it just be wetsanded?

-There are some holes in the deck that need to be filled, I have a welder that can weld aluminum, I can weld aluminum pretty good and do body work, but I can't fill in small holes too good so what options do I have?

-I want to extend the small front deck so I'll have enough room to mount a seat comfortably so how can I do this?

-I need to build a floor in it like the new Grizzly jon boats have any ideas and this boat has a small V all the way to the back so the floor would bend downward towards the center?

-I need to come up with a mount to build for a hand controlled trolling motor in the front where the boat V's.

I want to do everything without using any wood at all and do it myself. Any pictures would also help me out. Thanks.
