Proflex works the best if your looking for OEM sealant that can be applied over the factory sealant. I touch the area's up. If you tape the end closed you can re-use Proflex up to a few months.
Be very careful with Latex caulking, not all brands will go over the factory sealant and actually stick.
One trick I use is painters blue tape. Tape the seam and touch up. With a rag soaked on the finger tip wipe the seam. Remove tape immediatly. Nice clean tight lines like the factory
