Caring for the cladding is only as hard as you want it to be. I've never had an issue with Meguiars Endurance streaking in rain, then again I wipe all the cladding down with a clean old t-shirt about an hour after applying.
Here's a simple and easy way to get nasty cladding back to good:
Find a good shady area, preferably a car port, to wash the cladding. Use soft, clean cotton towels to wash the cladding with A mild mixture of Dawn liquid dishwashing detergent. This will get any grease, oil or was off the cladding. Once that's done, rinse very well. You can even drive down to the local self-service car wash and use the pressure washer about 3 - 4 inches from the cladding surface. You'll see what I mean if you do this. Then dry with some more cotton towels and if you have a super leaf blower use that to help get the water out of the crevices. Then go do something else for a while to allow the VX to thoroughly dry.
Come back and use a rectangular cotton applicator pad to start applying the Endurance Gold. Keep the pad liberally damp with the product and use smooth even wipes to apply. The edge of the applicator is good for getting into the nooks and crannies. Go do something else for about an hour when done, then come back with a clean old t-shirt and wipe all the excess off the cladding. This really makes the difference when using the Meguiars product.
That's it, your done for a few months or until you can't stand it anymore.![]()
