303 Products Rubber Seal Protectant – Protects & Conditions Seals on Doors, Windows, Hoods, Trunks Rejuvenates Color & Flexibility of Old & Dry Seals Weatherproofing & UV Protection, 3.4 fl.oz

I bought this in an effort to save an aging door gasket on a classic car...needless to say, getting a proper new door gasket was going to be a challenge and the "one size fits all" means "one size fits none". The product worked extremely well and the gasket is now sealing properly, without having to be replaced, definitely a win in my book.It may not solve all problems, but for just a few dollars it is worth trying before replacing an entire door gasket.

Works great for keeping the rubber on my old Philips Norelco shaver from getting sticky or drying out. Product is water based which means it's safe to use on a variety of different materials. Sponge makes application easy and efficient.

applicator will be a pain to use upside down, otherwise it works as designed and it is great just wish I could buy it as a liquid or have an applicator to do it with the bottle standing up not flipped over as I have seals 360 on my doors.

I bought a 24 year old convertible and used this product on all the rubber seals associated with the soft top, door seals and engine seals. I don't know how long the product will extend the life, but they look really good now and feel soft to the touch and not brittle at all. Seems to work well.

Arrived quickly, tried it, seems to work very well

Use it once a month on all the seals on my Jeep Wrangler. 9 years in, they still look new and plyable. Use on door seals and top seals on the roof. No dry rot, no cracking. Use light pressure and it goes on evenly.

it ok ..not super great ..the head design works well as applicator ..

Sticky rubber or plastic surface? This is the only thing I have found that actually works to fix that. So you know the horror of discovering something you have had for a while is de polymerizing and either becoming brittle or sticky. The brittle is bad enough but the sticky is worse as you cant use it without being reminded of what it shold feel like. So I have tried all the normal advice- soap and water (hah!), wife's makeup remover, olive oil, different alcohols (methyl, ethyl, iso propyl), Acetone, Armor All, Goof off glue remover, Goof off regular, nothing helped. In fact the regular goof off and acetone started to take off the rubber coating and made things substantially worse. I reluctantly asked ChatGPT thinking it would have no clue but it gave me some suggestions including this stuff. Its like old fashioned shoe polish- liquid in a bottle with a foam applicator on top. I tried it once and it was better. Not great but better. I let it dry and ran two more coats on it (Sweet Dell Xeon laptop from 2015) and to my amazement it solved the sticky problem and other than being glossier, its almost identical to my current Dell laptop. I beleive its a silicone based solution so it should not wash off as I need to occasionally wipe down the keyboard. I now have a whole range of stuff like tools and things that are next in line to get coated. It doesnt undo the damaged plastic or rubber due to oxidation over time and loss of polymerizers but makes the surface at least usable again. I have some automotive targets in mind as well. Fairly inexpensive solution to a vexing problem. No I didnt get it for free, I always pay full price usually after trying everything else that doesnt work but thats life.
