What I've gathered so far is
Esc - liquid tape or corrosion x ( voids warranty )
Shower caps - chassis
Plasti-dip servo's
What about the radio box ? Are you guys sealing it somehow ?
What about outerwear covers ?
Ive never waterproofed anything. but that's cause I could careless if it breaks. before I take it out, I spray wd-40 over the whole truck, play, then as soon as I bring it in I use a compressor to blow all the snow off, and wd-40 it again.
