yes i did search and read all the threads on possible ways to solve the problem. Most people say to dry it and reseal it. But what i dont understand is dont the headlights have breathers anyways? how would resealing them solve the problem if they are not air tight? A lot of people also say to add holes to help it breath more. which is more effective?

there are hairline cracks on my headlights. should i seal or drill?

 

bake the lens off and clean inside + reseal.
