Welcome: Honestly, that's the first I've heard of a C-pillar problem.
The TS I knew of the A-pillar/Windshield sealing problem over time as the Spider having sealing issues too.
The most common issue regarding front sealing is from weather damage to the 'rubber'/soft seal baking in the Sun etc. The seals are a bit on the steep side but relatively an easy fix to replace.
Spiders have more issues due to the up/down mechanics of the cover, but typically fair well .... most spiders/cabriolets have their tops down much more than ever up so the only factors are less pliability, creases, and rear window cosmetics.
