Advice

I recently got a 1980 mini. it is currently at the paint shop for a colour change. the previous owner had a welding done but painted it two tone am post green and blue. hopefully I will get it back in a couple of weeks. i have a few questions.

What is the best car cover to use?
The car has polycarbonate side windows is there a seal for door windows? as the doors are not watertight.
What is the most common seats to use?. I have 2 buckets and harnesses at present and they not the most comfortable thing I have ever sat into.

Thanks in advance
