Can anyone recommend a good product to
treat/preserve the door rubber weather-stripping?

Armor All?

Armor Al will cause the doors to squeak over every bump/twist. I would use a silicon spray from your local parts store yet. I have seen many people recommend electrical di-electric silicon paste, Like the kind that comes with a fisher plow.

ah ha!! Maybe that's why my damn door won't quit squeaking!

If you are going to use silicone spray, get a styrofoam cup and spray some in it first. If it eats the cup, then it isn't what you want to put on the weatherstripping.

Gm makes a product just for this. I'll see if I can find a part # or product name.

I use PRESTONE Silicone Lubricant( High Viscosity Formula ) Won't know how good it is for 4-5 years. The Texas sun eats that rubber trim and weather stripping up.I put it on twice a year.

GM recommends Dielectric Silicone grease. The part # is in the manual.

I second the dielectric grease. AAMOF, that's all I've ever used. Seems to work, with no deterioration of the rubber either.

I use dielectric grease as well. Worked very well on my 01 extended cab to eliminate squeaking. Don't have any problems with the 03 either!

I never used Armorall on my rubber components. I have been happy with STP Son-of-a-Gun for many years on gaskets, tires and weatherstrips as it is a petroleum-based compound versus silicone - doesn't evaporate away, squeak or deterioriate the rubber.

What do you guys use on the leather?

Dielectric grease for weatherstrip and Lexol for the leather.

I've used both Lexol and Eagle One leather protectants.

dielectric grease...nothing else. work in in good, wipe away excess
