Headlight restoration 50/50.

[Part-timer]

I let it cure over night inside the garage (at least 12 hours). I now put a few coats of sealants on them. We'll see what will happen the next rain. What do you suggest i should do?

I don't know what to tell you. I live in Daytona Beach Florida and only let them cure about an hour or two before the owners usually want to drive them home. I've never had any problems like you describe.

Would 2500 grit be fine enough to put this over? I want to try this on the camry headlights but do not have any 3000 grit.

Try it and let us all know.....lol (just kiddin') I've heard people on here only sanding them to 1500 and then coating them. I think to some extent, it's individual preference. I imagine 2500 would be fine. I personally take them to 3000 though.
