Interior slide gasket maintenance

[Mike-n-Sherry]

Getting ready for a big fall maintenance project on our 2013 V-Lite TT. I'm planning to use Protectall Slide Out Lube and also Protectall Rubber Seal Treatment on the exterior of the slides (unless experienced users advise otherwise), but I'm unsure about treating the interior gasket. I don't want to spray the Protectall Seal Treatment inside, but I guess I could spray it on a rag and wipe the interior gasket.
Is there another product that would be as effective for cleaning/treating the interior gasket?

I think that stuff is good for inside and out. I sprayed on small sponge one of those $.20 sponges from Walmart and then apply to the gasket.

After reading more about the product, that's probably a good idea both inside and out. Looks like overspray can be a problem, and wiping it one with a sponge would avoid that. Definitely worth a try- Thanks!
