Lube Gel for door seals or?

I just finished "mostly" cleaning old yellowed Lube Gel off my door seals.  Couldn't get all of it, but I got most of it.  I'm wondering if there is a better alternative, maybe something like B'laster Dry Lube that would also make a slick surface for the windows to slide on.

Neither.

I think in another thread I posted a GM P/N and a CRC SKU of the dimethlypolysiloxane lube to use on the weatherstripping etc. and as well posted that one can use DOT 5 (NOT DOT 5.1 -- only DOT 5) silicone brake fluid. DOT 5.1 is a glycol fluid, under no circumstances use it on weatherstripping etc. DOT 5 is a silicone fluid, works great for weatherstripping. Wipe it on. let it sit, wipe off excesss (after several minutes to an hour).

Polysiloxane grease. GM sells it "for corvettes" (ACDelco 10-4071) but it's mad cheaper and 100% the same stuff as CRC Dielectric Grease:

Do not use silicone spray. It *works* but the overspray discolors the plastics near the weatherstripping. You could use DOT 5 brake fluid, which isn't a glycol, it is liquid polysiloxane primarily for show cars, it won't damage paint, does not mix with other brake fluids. Dribble it onto a shop rag then wipe that on the weatherstrip.

Wipe th weatherstrip clean before you put the silicone on - no sense gooping the dirt into the weatherstrip.

Lube Gel used to be what the forum recommended. I had to go into a Radio Shack and endure a long, high pressure cellphone pitch at checkout in order to get it. Not surprised they went out of business, holy crap!

I think (someone on) the forum would have been mistaken to recommend lube gel. I wil explain.

If you look at the MSDS (this LINK), the RS Lube Gel is oil teflon, and synthetic hydrocarbons.  The weatherstripping, as described on Wikipedia (FWIW), is "...commonly made of EPDM rubber, a thermoplastic elastomer (TPE) mix of plastic and rubber, and a thermoplastic olefin (TPO) polymer/filler blend. Sunroof weatherstripping can also be made from silicone due to the extreme heat encountered by automobile roofs."

Silicone gel such as the ACDelko or CRC SKUs that I posted would not tend to degrade silicone seals or EPDM.  Lube Gel would, if only because of the petrochemicals it contains.  Just like you don't put Vaseline on a condom (if you expect it to do it's job...  ), this is one of those things in life that's pretty simple.

How about using white lithium grease spray? Is it good?

No.

Reason: Lithium grease sprays typically contain petroleum distillates and naptha. See for yourself, using Google do a search on "MSDS lithium grease spray" and read some of the MSDS.

For those of you not familiar, the MSDS is a disclosure required of most industrial and household chemicals (for instance do a Google search on "MSDS Lysol") that lists the ingredients in the chem composition, their flammability and toxicity.

I'll repeat what I posted before: the weatherstripping, as described on Wikipedia (FWIW), is "...commonly made of EPDM rubber, a thermoplastic elastomer (TPE) mix of plastic and rubber, and a thermoplastic olefin (TPO) polymer/filler blend. Sunroof weatherstripping can also be made from silicone due to the extreme heat encountered by automobile roofs." Silicone gel such as the ACDelco or CRC SKUs that I posted would not tend to degrade silicone seals or EPDM. Lube Gel would, if only because of the petrochemicals it contains. Just like you don't put Vaseline on a condom (if you expect it to do it's job... ), this is one of those things in life that's pretty simple. Same with Armorall - don't use it. Why? It contains mineral oil -- less than 5%, which is not enough to whack your weatherstrips quickly (like Vaseline on a rubber condom - it's quick and ghastly destruction) but enough to degrade them over time. Aerospace 303 is a protectant that does not have that little problem. I use Aerospace 303, and I wear gloves when I do because it contains antifreeze (ethylene glycol).

I picked some of this up but I haven't used it yet. Highly recommended by tom's turbo garage
