303 30324 Rubber Seal Protectant, White

Rubber window seals leaked on my car. This product helped soften the straight sections so they worked properly. Still had to use black silicon to seal the ends of seal where it gaped round the metal window frame.

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

Rubber seal to window

Never seen my rubber so shiny

Amazing product, great results can be used on all rubber.My only negative is that the picture shows more then one of these giving the impression that it's a mulit pack.

Used to condition and treat roof rubbers for a vw Eos. Before treatment one area of the roof was just pouring water in during torrential rain in December. 303 was applied by dabbing and spreading over all roof rubbers for a few days. This seemed to have helped during sibsequent bad down pours. Fingers crossed for the rest of the winter!

I used this product yesterday, as I had washed and cleaned my car the previous day. Left it to dry thoroughly, and applied this product yesterday, my seals don’t feel brittle and dried out anymore. I am even doing the rubber seals on my double glazed windows.

Used to clean rubber surround on car windows good result.
