Window-door gasket preservative recommendation

[lenjen]

I searched key words but did not come up with a topic that covers this. I noticed today that the gasket around the door on our RV has pulled back slightly in the upper corners. Does anyone have a product recommendation to prevent the drying and shrinking?

I use protectall with good results. Nothing will stop them from shrinking though.

303 for me.

Thank you for your replies. I will check into the Protectall , my DH has some in the garage.

I went on the 303 site and ordered there sample kit.

I use 303 on my 18 year old Dodge Ram once a year and I still have to crack a window to close the doors on the first try.

Available at auto supply. Works good lasts 6 months.

What happens if you forget and go over 6 months?
