Well I kind of went overboard on mine just because I planned on keeping it for a while and then handing it down to my son eventually. I bought the sandblaster from Harbour Freight because I already had the air compressor. Got the blasting media and new fenders from Tractor Supply. Bought new aluminum rims and tires(bought 3 so I'd have a spare), hubs, bearings, leaf spring kit, trailer coupler, light wiring harness, led lights and tounge jack from etrailer.com. Winch, winch strap, and spare tire bracket from Wal-Mart on clearance along with the bed liner paint I used to paint over the galvanizing with. New yellow pine 2x6's from Lowes for bunk boards and stainless lag screws. Bunk board capet from boatcarpet sales on ebay. If I'm not mistaken adding up all the stuff I listed above along with what I paid for the galvanizing and welding I had done before hand I've got about $1800 invested in the trailer. I could have bought a new trailer probably I don't know but this one is the same as new and I know what's in it. That's not counting my time and transporting the stripped down trailer on my big utility trailer I have. In order to have it galvanized you have to strip the springs, axle, all bushings, wiring, and lights off. Then all the paint has to be removed. Then you have to drill holes in the bottom of the trailer ever so often as well as the cross members so the liquid can flow thru and drain back out. After all this they still can't guarantee that it won't warp it when they dip it. This was a chance I took though because I didn't have much invested in the boat and trailer and my trailer was in bad enuf shape it probably would have only lasted about 3 years if I hadn't done this. The galvanizing itself only cost me about $140 including tax.
