Likewise. All Bilt Hamber products come out top in tests/reviews. Underbody, releasing agent, waxes etc etc. Never saw the need to use anything else. Tried a few over the 40 + years of owning classics/hobby cars. In winter, I am careful how I use them. Maximum one month at the outside between drives and try to pick a dry day. I find not using hobby cars daily makes it a more special occasion when I do. I have a couple of workhorse daily drivers, (Volvos) which seem impervious to the ravages of winter roads. I keep my hobby cars as nice as possible but hate washing them!
