Tired Taillights

I've messed with a few old ( mostly 1960's) MOPARS & trudged through a few Kentucky & Ohio junk yards searching for parts. Give me a cigar & a machete & I'll go on a hunt. I enjoy that as much as some of my friends enjoy fishing or golf. Recently I came across a couple of '66 Barracudas with the obligatory tree growing through the engine compartments & other signs indicating they've been there for quite a while. I've pulled off a few pieces to experiment with and have become particularly interested in the challenge of restoring tired, faded, (but still intact) plastic red tail light lenses. They're faded to an almost pink color on the outside & are spider-webbed.
The insides are still as red as new. I've begun experimenting to find the best technique for removing the top, faded, spider-webbed part in order to make 'em look like new. I'm sure I'm not the first guy to take a shot at this - so rather than re-invent the wheel, I thought I'd ask what any of you have done. With all of this Corona virus thing going on, I thought it would be the time to do something productive. Anyone?
