Baby powder on slide seals?...what if it rains?

[tankcj]

With the research I've done, it appears that the baby powder applied to slide seals just keeps them from sticking but doesn't do anything to treat or preserve the rubber...Correct?...

If you are using the baby powder on the exterior seals, what happens when it rains (or you wash your rig) and your slides are open? Do you reapply?

I can see using the baby powder on the interior seals but was thinking of using 303 Protectant (i've used this stuff for years) on the outside while the slides are open to help protect them from the elements and then maybe apply baby powder to the exterior seals just before closing up for travel. I may be overthinking this....

I use 303 on all my rubber seals, and tires. I apply every time I wash our rig.

X2 on the 303, also can use Amorall. I can not imagine
a set of circumstances where baby powder would be
of any use.
