me and my brother are moding up our old 14' jon boat and i have a couple quick questions.

1. Which is better for framing 2x4 or aluminum l angle?

2. What thickness of marine grade plywood is best 3/4, 1/2, 3/8?

any help would be great

forgot one

what is the best kind of paint to use?

I like aluminum L angle but then I also like welding every thing together  

2x4's add a ton of weight, any option you have will likely be a better choice.

3/8 or 1/2 in is plenty as long as it is braced properly

I use Interlux yacht paints.  Not cheap but second to none.

I use 2x2's with Simpson Strong tie Brackets. It saves a ton of weight and if you use 3/8in ply it will hold up a truck. Check out the sticky at the top. It might give you some ideas.

fluke i got done looking through your project and i very impressed thats a good lookin rig you made.

I think im going to have to go with the 2x2 and strong ties, it fits my skills the best. I'm gonna get my pics up pretty soon so be ready
