Update: Trailer is as finished as its going to get right now. I got some overspray on it while painting the hull but its just going to have to stay for the summer.
I did lots of sanding, spent lots of time with a wire brush, and still need to do a little more on the interior, but the hull is painted. I wiped the hull with acetone and then I primed the entire exterior with 1.5-2 coats of spray can self etching primer. The exterior has 4 coats of parker coatings duck boat paint in hunter green and the interior has one, sprayed on with a wagner sprayer. Worked awesome.
Note on the primer: I used both duplicolor and rustoleum self etching primer, and have to recommend the rustoleum. It provided much better coverage, the duplicolor is very thin and will run if you spray it on half as thick as the rustoleum, I might have gotten some bad cans of duplicolor or something but basically it was far inferior to the rustoleum in my opinion.
Note on Parker coatings duck boat paint: I bought a gallon for like 33 plus shipping and four coats on the exterior, one on the interior have over a 1/4 gallon left. Note this is by spraying.
I plan on doing some more finish work to the inside of the hull then brushing/rolling on another coat or two.
Here are some before pics, some progress pics, and pictures of how it sits right now:
Those last few were some I snapped with my phone.
Next up: Finish painting the hull interior as noted, then get a floor in this thing. Both of my motors are at the mechanics getting a tune up, should be back pretty soon.
Floor:
I searched the site and didn't even find a mention of advantech which surprised me a little, but I have three sheets of it and I'm going to be the guinea pig and use it to build my floors out of. I think it is really good stuff and I'm pretty confident it will last a very long time. This stuff is nothing like osb, don't let it fool you. Check out www.advantechperforms.com
I'm running low on funds so a floor might be all it gets right now. I already have the advantech, the carpet, and 8 treated 2x2's so we will se how far that gets me.
EDIT: I have realized since I bought treated 2x2's that they will corrode the aluminum. Mistake #3
