repainting a jon boat

I disagree about priming, especially a high build primer. High build primers are for those interested in fairing and smoothing operations, which most don't bother with on a boat like this. With the exception of some of the really expensive paints (read $300 and up), most will go over a toothed, well sealed, well attached top coat.

Painting is all about the prep, not the roller in hand time. 90% of the effort on a good paint job is surface preparation. A jon boat doesn't need a lot of prep, just tooth it up with 120 - 180 grit and apply a top coat of choice. I'd recommend a single part polyurethane, so you don't have to offer up your first born son to pay for it. At least two relatively light coats, three or four are better, if you expect to beat the crap out of it, which jon boats seem to endure.

If not interested in paying "marine" pricing, than use an "industrial" or "farm" equipment type of paint, like that from Rustoleum. They're single part polyurethanes and work well, for much less.

 

Thanks to everyone for your help, I'm going to try and get it painted next weekend. Thanks again.

 

Thanks again to all who gave me advice on painting tmy boat. I told you I would get some Pics, so here are a few.. of what I have so far. put 1 in foam sheeting (not shown) between the ribs on the floor. put shower panneling as the base floor, and waterproofer the back of the pannels with rubber. You can get the rubber at home depot. its for dipping tool handles in to put a rubber coating on. I used a trowel. I framed everthing with aluminum to keep it light weight. The platforms it self is sign material you can get at most custom sign shops. It's 1/4" thick and lighter than the shower pannel and stronge the plywood. I let the top platform hand over a few inches and mounted small LED lights under the lip and it gives off a nice light at night so you can tie lines and bait hooks, without drawing in alot of bugs. I have running lights, spot lights, buildge pump radio, cigeret lighter for cell phones or what ever, a blue transom light that is mounted under the water so at night my wake turns blue(super cool) live well and aerator. I have put plates in differant places around the boat so you can move the seats, jusl lift out the seat and pole and stick in a differant place.
I'm giong to try and get it painted this comming weekend, then all ill need is carpet.
