A sand and clear coat respray doesn't work. It is something looks okay on video, but is embarrassing in person.
First, if you can see where the clear is cracking and flaking off (crystallizing is the industry term) with the naked eye, then you need to understand that all the paint has begun to crack down to the bare metal base with tiny cracks that only get larger and crack with time. No matter what you paint over them with.
It is impossible for a person to sand off the clear without sanding through the base color all over the place. Ignoring that, every area where the clear is crystallizing and delaminating is going to be a different ring of paint damage that will show up under fresh clear like a water stained piece of paper. Go from the area in the center where the clear has already come off- that area has UV ray damage that is discoloring the base color all the way down to whatever is the next material layer underneath (sealer, old paint, etc.). Now go to the patch of clear that is crystallizing (usually about 1/4 inch wide). If you can sand that off without going through the base, then that area is permanently discolored in a different pattern than the center area mentioned before. Finally, every area where the clear is sanded off and revealing base coat underneath will have a discoloring ring when it is clear coated over.
I don't say any of this to crap on your hopes. I want to save you heartache and embarrassment.
Couple other items.
To find a paint striper-go to a local motorcycle or custom car show and ask around. You should get plenty of referrals there.
Solid color 107s did not have clear from the factory. Mercedes-Benz didn't clear coat solids until the early to mid 1990s, IIRC. Safe to assume your car has been painted (partially or overall) sometime through the years.
I hope this helps. I will stop here for now.
