Ok, heres the deal on Dry Lubes, The Home Depot stuff is called RZ-50, it contains no oil and no silicone. It sprays on and drys in seconds, I used 3 coats.
Another I have is Liquid Wrench Dry Lubricant. It is sprayed on and you have to wipe it down when it is dry, takes a few minutes to dry.
I have no test results yet, but I coated one dish with RZ- 50,my other dish has a small trash bag over it, I sprayed the bag and LNB and arm with RZ-50. It is supposed to snow here tomorrow and Sunday, I will report results.
Another test is on my snow shovel, I sprayed one Dry Lube on half of the shovel and other Dry Lube on other half. This is an all plastic (ABS) I think, the shovel has many years of use on it and rarely has snow stuck to it.
