Also, I block up the axles on my altereds if it will sit for several days.
Also also, in Ford's assembly plants they had a product called "murple" (get it?, it is the only word that rhymes with purple). It was used on hoses and vacuum lines as a lubricant but after installation it dried and acted as an adhesive bonding the rubber to the nipple. I hesitated to mention that initially as I do not know if it is proprietary or available commercially. There may be a similar product on the market.
