Why does windshield coating wear off in Seattle?

Short answer

Wipers. Ceramic Pro Glass is rated for one year, but in Seattle your wipers run so often that the friction wears the coating down sooner. APC Auto Spa recoats the windshield free of charge, as many times as you want, and it takes about 15 minutes.

Why do wipers wear the coating?

Every swipe is a rubber blade dragging grit across the glass. In a dry climate wipers barely run. Here they run for months, so the coating gets worn down much faster than the paint coating does.

How do I know it's wearing off?

Rain stops beading into little balls and flying off at speed. Instead it sheets across the glass and you lean on the wipers more.

Is it still worth coating the windshield?

For many drivers, yes. A fresh coating makes a real difference on a dark, rainy freeway drive. The trick is keeping it fresh, which is why free recoats matter.

How APC Auto Spa does it

APC Auto Spa recoats the windshield free of charge, as many times as the customer wants. It takes about 15 minutes to clean the glass and apply Ceramic Pro Glass.

Whenever rain stops beading well. Because recoats at APC are free, you can come in as often as you like.

Will new wiper blades help?
