just rust proof it with silicon spray pb blaster gragrage door lube works great.Goes on than drys you can get it at yourlocal hardware store. Its like 2 bucks ,spray it on every thing even plastic the sand will just fall rite off. When your done bashing just use an air compressor and blow all the sand off,then use wd-40 on the wheel bearings.Dont let people scare you its all in how well you mantain your rig.
