Question

my plastic headlamps on the upper half are becoming opache....bottom half are not too bad......is there any compound that i can use with a cloth to bring it up clear again ?

there are a few u-tube clips but im very suspisious of them................

Wet and dry them with 800, then 1200 then 1500 grits and 2K lacquer them which contains a UV filter to keep the Polycarbonate clear for a good few years. If you don't want to lacquer them use even finer grit then rubbing compounds before T cut. 

You won't need me to tell you not to apply lacquer to polished surfaces but some mugs believe everything they see on youtube.

Tooth paste or wood ash, not a permanent fix but it only takes a few minutes to clean the lens nicely.

As above, wet and dry, plenty of soapy water.

I have to do my 20 year old Xtrail every year to make it presentable for its MOT, I used a mop on a power drill with cutting and polishing paste this time around which worked easier but made a bit more (lot more) mess, lift bonnet up out of the way and mask off surrounding paintwork such as bumper and grill.

Waxing afterwards lasts a while if not wanting to spray laquer

Tru Grit superfine is perfect for plastics and acrylics.

Easy to apply and buff with a mop on a drill, and watch the haze removed.

A little goes a long way and is used on my acrylic pens.

If you want some to try, I will pop it in the post for you 👍

I use TCut or UPVC restorer whatever I grab first. 
 

usually a clean before summer then one at the end. 
 

I have been doing this for about 6 or so years.

All of the above will work.
Just be careful if using a machine polisher, the plastic surface will only take so much heat before permanent melty damage can occur !
