I replaced some trim around a window when I was painting my house a while back. I caulked it with 100% RTV silicone. It had been sitting in the garage for a while and was apparently past its shelf life because it never cured. I bought some new stuff and it set like it should on another window I did. Silicone is kinda a pain to clean up so I have just left it as is. I'm curious if there any common chemical I can maybe spray on the uncured RTV that would make is cure?
Today I just got done welding up the cast aluminum oil pan on my car since I it on a rock on a dirt road this weekend. Its beyond me why they went with cast aluminum that cracks and leaks vs stamped steel that bends and holds oil. Welds turned out ok but was hard to keep the porosity at bay due to having been contaminated with oil all its life. Pan holds water and does not leak but I figured I would put some RTV over the welds for good measure. RTV is not setting up... Going to pickup a new tube but got me to thinking sure would be nice if there was a way to make old RTV kick.
