Hi Dick and Mary
First off welcome to Sunline Club. Glad to have you with us.
For the slide seals, I use this product. Both on the inside and outside seals. 303
It has UV sunlight blockers and helps keep the sun from bleaching out all the plastizers out of anything plastic or rubber. I also us it on the rubber EPDM roof, the fiberglass cargo hole doors, the vinyl awning, vinyl trim, tires, entry doors, oh yes, the decals. The roof vents and the plastic surrounds inside of the roof vents, the shower dome, the fridge vent etc, anything plastic, vinyl or rubber on the TT.
For the slide seals they do make products that claim to be just for them. And they work OK too, but what they are doing is the same ting,. UV protectant to keep the sun from killing the seals. And that keeps the seals more pliable so they do not crack.
They sell 303 in many sizes. Since I use it all the time, I buy a gallon of it and a good squirty bottle that has a decent sprayer on it. So far Iím now on my 2nd gallonÖ. A gallon last me oh say 2 maybe into the 3rd year.
Any time I use Awesome to clean the TT off of those nasty black streaks, I redo the plastic with 303. The Awesome works great, but it also strips any wax or anything off in the process.
Good luck and hope this helps
And again Welcome.
PS what model TT do you have? You sig only mentioned a 2007. We are a curious bunch here on Sunline club as we compare stories etc on camper models and are a self help group now that Sunline is no longer.
