I started using Sikaflex elastomeric on our last trailer in an attempt to keep the caulking white.
The dingy look drove me nutz.
I would scrub the old caulk with touch of TSP and a poly scrubber then re-strike with Sikaflex.
*caution
TSP can remove paint rinse water should be kept close at hand.
I've used proflex and sikaflex but neither last as long as Wurth Bond and Seal. Wurth Bond and Seal is great stuff, it definitely lasts longer than anything else I've tried. The biggest difference I've noticed is it doesn't seem to pull away from the surface like the other two products mentioned.
