That method is likely quite ecologically disastrous, Ig.
Perhaps not as bad as cad, but using something which does not wash off
would be better.
How about lanolin based underoil spray? Or vegi based. I prefer the
lanolin - like Fluid Film, or NHoilundercoating, A friend operated an
undercoating business for years, and he mixed lanolin and paraffin
hot, and sprayed it on underbodies. Quite a few "proprietary" dripless
underoil products have lanolin and no petroleum products.
