Just finished waxing, bought some Liquid Wrench Silicon, "it want hurt" paint, did steps, the landing gears and plates at the bottom, front door and all slide gears including the four on the bedroom slide. everything is gliding with no friction. The old silicon spray I got from Camping World dried with a yellow color. Liquid Wrench is clear. Flushed all tanks including fresh water tank. Have to grease all the fitting on the axle and suspension and I'll be done.
