If all goes well I'll be getting the HF 1175 frame this weekend and starting on the construction. I had intended on making the frame out of 2x4 and 5/8 sturdifloor. After bolting it to the trailer I was going to have the bottom sprayed with Rhino truckbed liner. However, my Home Depot has 5-gallon buckets of foundation sealer on clearance for $1.00 and I think a couple coats of this stuff would build up a thick waterproof coat very much like Rhino. What have others done with the frame/floor for sealing?
Also, for the HF trailer itself, is the baked red paint finish a decent finish or should I consider priming and repainting it also? I'm not sure I'll like the red anyway but I'm more concerned with corrosion prevention. I was thinking Interlux InterProtect 2000 epoxy primer then paint. All comments appreciated.
