Paint sealant durability?

[BrutalNoodle]

It's true though.....
The previous day before it snows, I've put down sealants and waxes and combos of the two on the car and the next day I drive to school and work, come home, and the next day I go go the coin op and rinse the salt off with high pressure washer with water- not soap- and see zero beading in the area affected by the salt. Which is the fenders, lower door, rear fenders and trunk.

Have you had any luck with any sealants or waxes?

This might be a good time to experiment with pre wax cleaner/paintwork cleanser.

Something could be interfering, preventing proper bonding of the wax/sealant. It's worth a shot, plus makes for a good learning experience.

I have used DG 105 in previous winters and put my car through at least 15 commercial touchless car washes during the winter, and yes our roads are salted. The DG 105 wasn't even phased by it and in fact once May came around I still had protection. A year is unlikely for any sealant but you sure as heck can get 6-9 months easy even with salted roads. FK1000p also lasts and lasts.

We've been having a similar experience with DG111 on my gf's truck, and with DG 101 on both my Mom, and Dad's cars.

You mention applying the sealant the day before it snows. Are you following the manufacturer's directions? Perhaps the curing times could be affected by the cold weather and you're not getting durable protection?
