Hi All,
I bought a complete set of all seals for a 2 door RS from Scotts old Auto rubber. Got the solid ones for the RS and are great fit and quality. They also sell a special rubber conditioner which I have used on all my screen seals and keeps them in as-new condition - the UV in this part of the world is horrendous- our local weather station gives a uv rating everyday like the Richter scale - up to 15 in the summer but thankfully down to about 7 or 8 in the winter.
