Re: Using Spray Max 2k Clearcoat on headlights?
I would say that 200 grit is way too aggressive to start.
I'd go 600, 1000, 2000, and see where you're at.
Clearcoat is funny sometimes, as it doesn't always fill like it should especially on clear plastics.
I'd recommend polishing them out with a compound and polish too and then using something like Optimum's opti-lens.

Re: Using Spray Max 2k Clearcoat on headlights?
Welcome! I see this is your 1st post on AG.
Have you considered going with a headlight lens correction kit instead? An AIO product is going to be way more user friendly and forgiving then trying to jump right into sand out your headlights and then spraying on a clear coat. As Mike Phillips always says: Always start with the least aggressive approach first.
Honestly if you're new to this, I'd strongly recommend a product like DP's Headlight Kit. Check out my review on the using DP's AIO on a toasted set of headlights:

Since you're already planning on getting a DA, you can enjoy the same results without the risk of too aggressively sanding your headlights / getting clear coat over spray onto your paint...

Re: Using Spray Max 2k Clearcoat on headlights?
I'd say your plan sounds good although I'd probably start with 320 in lieu of 200. 600 is adequate for the final sanding before the clear coat.
Like others have said, have you tried polishing? That would be my first choice. If that doesn't do it then proceed to sanding.

Re: Using Spray Max 2k Clearcoat on headlights?
I've restored headlights before and am not new to painting or wetsanding, just haven't used 2k clearcoat before. I want something that will last and to do it right the first time. I was going to use 200 grit to make sure I get all the clearcoat off but 320 sounds good too.
The other picture doesn't show how bad the headlights are, here is a better picture...
Definitely past the point of a simple polish
I was going to go with 200 after reading this DIY on corvetteforum

Re: Using Spray Max 2k Clearcoat on headlights?
Now I can definitely see how bad it is. There are times I wish I had 200 grit.
I don't have experience with 1 or 2K clear but I thought I have read to finish sanding around 1000 for clear coats. Maybe higher.
You can use 2000 grit to sand out your orange peel if you have any after clear coating them, but you might want to step a grit or two lower to speed up your results. Then finish up with the 2000. Also would depend on how severe or light the orange peel is.

Re: Using Spray Max 2k Clearcoat on headlights?
I thought I read somewhere that the clearcoat will even cover 400 grit sand marks, I basically want to go as low as possible to where it still covers the sand lines...that way the paint has a great surface to grab onto

Oh yeah, from the new photo/ better angle those headlights need sanding. Good luck!

Re: Using Spray Max 2k Clearcoat on headlights?
I haven't had a turn on a Viper yet but most Chrysler plastics are easy to work with. It looks like a good portion of the coating is failing so 1000/800 may be a good starting point. 400 would be my next approach. Please post some after pics of your work! Out of curiosity, have you priced out lenses on that yet?
