Using Extreme, Super, Heavy cut compounds for Headlighs?

[Mantilgh]

Just found this on the "Featured Items" at the AG store site.

Meguiars Unigrit Sand & Clean M31716

I guess this is a new product, little info on Meg's forum from back in Oct/Nov. Might be what they are using in their new headlight kit or at least sounds the same; matting compound used with a scuff pad.

No claims to what grit it would be comparable to or grade of scratches left behind.

I do have some more tests coming once I get some reasonable weather. Decided to make some of my own pads; one closed cell foam and a double sided compressed wool.

Well, made a few pads with nothing invested a little success. Pad delaminated after some increased heat and pressure with the rubber contact cement used. Then thought some more.

I really like how stiff the CarPro blocks were that came with the kit and really want to try the 3" ones when I can, but can't get right now. Then thought, why not turn one of the two CarPro rayon blocks(if they are the same material as the 3" pads) from the kit into a smaller disk.

Pealed the rayon part right off the foam block, and went to work on it and my broken 3M backing plate.

Cut the pad as big as I could and ended up with a 1 5/8" disk.

Some epoxy and some left over plastic radio trim was used to make my new backing plate from the broken 3M one.



Everything after all epoxied and clamped together. Also pictured is my modified CarPro rayon pad with an old piece of 3M 500 grit epoxied to it for the "loop side" which was something hard it find suprizeingly.



With the "hook" side that was removed from the 3M foam backed plate.



What I ended up with for now. Can always be made smaller if needed.







Have not had a chance to try out yet.

Bump to an old thread
I've also been trying to find ways to avoid Sanding steps or atleast make things.no more then a 3 step when dealing with a crazed headlight

Most aggressive combo over.used that was on hand was carprp Cool wool hybrid pad and S3 XXL(may work well for pitted lens)
It reduced crazing, but didn't remove it
I'll be ordering S0 and see if that does the trick
Also found Menzerna liquid sand paper(equivalent to 800-1000 grit)

Plan to also try meguiers liquid sand paper and clean product..
If non works for at least a quick 2 step
.then I'll start off with 320 or 600 then do the steps one of the products mentioned followed by S3 xxl

No progress here.

I've been grinding away at the bad ones using 500 and 800 grit disks to start out with when needed, then hand sand with a foam block up 2000. All the corners and hard spots by hand. Then compound, polish, coat.
