It is nice to hear from another Oyster interior corvette. I have a 78. On the seats I purchased replacement skins. It is a very simple process to take the old off and install the new. I choose this path rather than dye.
I did purchase dye paint for several of the plastic pieces. I don't understand the issue with sending you paint. I just checked UPS and it is allowed.
If I can help, let me know. I travel to Darlington,Daventry, Kent and several other locations in the UK several times a year.
Always willing to help a fellow Oyster guy.
