Hi from rain/sleet/snow belt,

Spent a while doing inventory taking in various stores, funnest job was at West Marine where they have lots of heavy duty stuff, paint, electrical, etc., stuff intended for "below water line" applications. Expensive, but what you see there can be purchased for less at home depot et al.

Present '83 245 spent >15 years in mild s. Cal climate, much of car looks new but rubber doesn't hold up forever. 8 yrs. here in NE are showing their toll and the kali beauty isn't watertight anymore.

Have had good success over the years with Ohio rustbuckets I've owned, sealing up various gaps with "butyl rubber" gutter caulk. Comes in tube like standard latex/silicone stuff, but is amazingly sticky and will adhere to ANYTHING, very water tight. Kind of hard to work with (keep solvent soaked rag handy), but what do you want....only available in white, maybe black, not clear to my knowledge. Takes a long time to cure, a drawback when its 34 deg outside.

Says on the tube, "ideal for sealing truck/trailer" bodies. Used some just yesterday to glue/seal in clear lens at back of wagon that had come out, had come unstuck from previous owner's attempt w/ clear silicone which had lost its grip after 2 yrs.

Silicone spray around old dry brittle gaskets helps to milk things a bit longer too, I suppose you've tried that.
