I am very impressed with the Profi Line from Sonax. That means I have applied to 5 years "aged" plastic strips and rubber seals on my car. The gel is easy to apply with a soft, absorbent cloth. It is very well received by Kund fabric / rubber. As long as it has not yet become due to aging porous (porous) the treated material like new looks. It is then very supple and a rich and silky gloss. A little tip: a soft microfibre cloth removed the gel from car paint readily if you could apply not quite area exactly when applied times.
