For Slide Seals - 303 or Thetford Slide Conditioner

I've used 303 Aerospace Protectant on the slide seals for the last 2+ years and it seems to be working okay. Only on the outside - did not know about the inside seal. The only thing is that it seems to remain tacky after use since there is really now way to wipe it down. I just ran into the Thetford Premium RV Slide Out Rubber Seal Conditioner and Protectant. Looks like it might be better and about the same price. Has anyone had experience with it? Is it more of a lube for the seals? How many 15oz ($5.93@AMZN) cans would it take to do 5 slides, in & out?
