Oldy but Goodie
 

This came out of a 89 XJ6. It was in a car under 3 others. My eye caught it when I was at the boneyard in February, due to the snow and ice I couldn't get to it. I was able to just reach my arm in and muscle it out. It was white, cracked and the cellulose lacquer was gone. I just filled the cracks, sanded it and used some varnish then some clear coat. It has life again in my 90 Sovereign.

That looks pretty good - wish it was as easy with a cracked ski slope - had to change mine.
