  • ISO - Rubber Seal Conditioner / Lubricant

    I'm looking for advice on the best conditioner or lubricant for rubber seals.

    My 2015 F150 has one of those panoramic sun roofs. (It was on the lot, what can I say, I don't ever recommend a vehicle with a sun roof, especially a Ford product, but I digress.)

    The sun roof has had never ending multiple problems and the Dealer is unable to fix it. No joke, I've had it in 10 times for sun roof issues. They have taken a crack at themselves, supposedly brought in an "expert" from Ford, and sent it out to trim shops. The problem has never been repaired, never been addressed. I don't even know if they have honestly ever done anything. (Let's face it, once they have your money, they could care less and unless it's remove and replace, they don't have a clue how to fix too much. (And they are not about to remove a replace my sun roof.))

    The problem is never ending rattles and squeaks. It's all very much weather dependent as well with squeaks in the cold, but rattles in the warmer weather. It never does it when it rains or there is snow on the roof.

    In desperation, I have taken to the internet and found out, I'm a long way from alone. Obviously Ford has a design problem. (Though unlike a lot of other people on line who post that their dealers claim that theirs is the first they've ever seen this problem, my dealer readily admits that the problem with these large sun roofs is quite common.)

    Anyhoo, one guy on youtube posted a video of the exact same F150 with the exact same stupid panoramic sun roof with the exact same problem and claims the same frustration with Ford, but also claims he has cured the problem by applying lithium grease to the rubber seals around the perimeter of the sun roof to condition the rubber. He claims success. At this point, I will try anything because these multiple rattles and squeaks are driving me nuts. (Open the roof and all the noises go away.)

    But I'm not so sure about conditioning the rubber seals with lithium grease. (Rubber doesn't usually like heavy grease.)

    So I'm wondering what is on the market that will condition a rubber seal without deteriorating the seal???

    Or maybe a light skim of lithium is ok. I dunno.

    But this nonstop squeaking and rattling has to end. Ford sure as hell doesn't care.

    Lithium grease is a 'light'/ thin grease, it should be okay- just rub it around with your fingers.

    Also, if you can find it online, a clear silicon grease makes a good, non-intrusive, lubricant.
    Most auto parts stores/ flaps don't carry it; it is considered a specialty product..

      Is this what he used ?
      I don't find it all that thick, unless you let it pile up.

        I use a rubber lubricant called "P-80", but i think its more of a temporary assembly lubricant. For a "conditioner", i think silcones are usually considered better. One such product is "Sil-Glyde", often used for rubber brake parts.

            I’ve used this to solve a few squeaking issues on the rear gate in an SUV. Makes the rubber seals look good too.

                Thanks guys for your suggestions.

                I went to NAPA yesterday, but buddy said they only carry Sil Glyd in US stores. But they had a silicone based lubricant by Kleenflo that is supposed to be an equal. I am going to give it a shot.

                Sil Glyd is available on Amazon though.

                Hoping it does the trick.

                  If you have a nearby civil airport, they may have the dow corning aero products. DC-111 or DC-55 are both grease consistency silicones. Some others are basically hydraulic fluids (I forget what those callouts are). That isn't to say that they're safe on the rubber in this application. These can also be ordered online. Also, a restaurant supply may have food grade silicone grease on the shelf.

                    How about the red rubber grease used on LBCs, which I believe is plant-based? Otherwise I'd try a tube of a silicone grease like Super Lube Synthetic Grease. That is sold at Harbor Freight or online and maybe even your FLAPS
