Acetic acid in silicone sealant damage?

[LiamG]

We have pretty limited options in Canada at the best of times but the local hardware store has this rubber based sealant which is similar to parabond. Any thoughts on the Lexel brand?

That was 20 years ago, I reapply every spring thinking I'm going to remove the old sealant some day.
I'm now thinking the kids are going to inherit it with a can of wax and instructions.

Carnauba wax is a great idea. Now I wish I had been taking better care of my Expedition and had some around!

I have been using Lexel instead of silicone for a few years, wherever I would use silicone. But, I never used silicone on the exterior.

I carry some butyl tape to temporarily fix a leak.

I’ve been using this on my Airstream and have been very happy with it.
It available at any hardware or home improvement store and comes in grey.

I’ve been using the Luxent and it’s messy but fairly easy to work with.

When do you normally replace sealant? I have some that’s cracking and falling apart that I’ll obviously replace but others that look old and dry yet aren’t in terrible shape and are vertical along the sides of windows (see photo). Would you redo them all?

I used Captain Tolley's Creeping Crack Cure

Used 2 to 3 applications around the windows...👍
Nice thing...It all but disappears into the crack.

That’s a fantastic looking product. Next time I’m south of the 49th, I’ll be sure to procure some. Hopefully the border opens soon to nonessential travel!

No real need to scrape the old stuff out...🤔
I wiped the cracked original sealant down with mineral spirits, and let each application dry,(it's clear dried). It will usually take several applications to finish.

Good Luck...
