303 Products30324 Rubber Seal Protectant - 3.4 oz.

use this for door seals on my wife’s car to prevent ice from making the door windows not move when opening the door. Also use annually for port and hatch seals on a sailboat. Used for many years and works great!

Easy to use applicator, I use it once a year on the door seals on my camper to keep them pliable and soft.I use all the 303 Products, they just work.

This is my second purchase of this product. Used regularly. Seems to be exactly what it says it is. No complaints.And the built in applicator is a bonus even tho it is somewhat difficult to use in some of the more hard to reach bends and curves.No complaints, and satisfactory performance.

This product works very well - I’m thrilled. My three year old car driver door and sunroof were making annoying and loud rubber noises on every drive. This product silenced that after one application. I admit to being very skeptical. It works. Highly recommended.

My sisters truck rubber around the window was really bad and turned your fingers black when touched. This worked great at conditioning it! Love it!

I think this does well. I have not had it long enough to tell.

I have a 1969 Mercury Marquis Convertible. Unfortunately for me, there are no aftermarket or oem convertible top seals available for my car. Therefore, I have to make do with what is still on the car. When I bought the car in 2019, the seals around the windows and top were dried out, cracking, and some loss was already occurring. I found this product and started using it hoping to restore my seals so that they last until someday aftermarket seals become available. As of 2022 they are still not available, but after a couple of years of using this product on the seals, they have returned to a flexible spongy seal again. No longer dried out and starting to crumble. I don't drive my car in the rain (willingly), so at this time I don't know how well the seals are really working, but I am SURE they are better than when I bought the car.

Great stuff. this juice will make old hardened rubber moldings become pliable again. Don't care much for the sponge applicator on the other hand. Hard to get it into folds and narrow rubber moldings, like around the wing vents of a 66 Chevelle.

Pour mes véhicules

Tengo una chaqueta moto RUKKA ARMAS y para quien tenga una. ya sabe que la cremallera es cierre hermerico y de goma..Le he dado y va perfecta .ya veremos con el paso del tiempo.También le he dado a las gomas de las puertas del coche ya que se quedaban pegadas y de momento no se pegan.

The seals around the convertible roof on my Merc had began to harden up and drip, after reading many reviews, I settled on this product and it's done the trick. Simple to apply, and I have done 5 so far but the rubber has become more flexible and is creating a water-tight seal, need to remember to apply it several times and the seal needs to be clean. It can drip a little so be careful, but it's sorted the seals and beats replacing the seals at £400 plus. Recommended

Di facile applicazione. Ottimo

Il n'y a qu'un flacon, ce qui donne un prix au litre qui est astronomique.De nombreux autres produits sont "rubber sealants" à des prix plus raisonnablesJe n'ai pas essayé le produit mais je ne vois pas comment il ferait mieux que la concurrence dès lors qu'il est presque 10 fois plus cher.
