Frequently Asked Questions (FAQ):
I applied the clear coat, but it became cloudy once dry, why is that?
Ensure that protects you used were compatible, the degreaser was fully evaporated, and no moisture came in contact with the fresh clear coat.
Why did the clear crack or crinkle up after drying?
This is cause from a chemical reaction. Your headlights could have been clear coated in the past and the new application of clear coat wasn't a compatible product. Another issue is that you may have used incompatible products which would also cause the same effect.
What type and brand of clear coat was used in the video?
The type is acrylic lacquer and the brand was Dupli-Color.
How long does it take for the clear coat to harden before wet sanding?
This will be dependant on your climate and how thick of a coat you applied. As a safe time span, a week should be a sufficient amount of time.
Will this method work on glass?
No it will not.
