In 85' I finally replaced the broken, cracked and aged lenses. Bought brand new hella's for the front and rear. Been working on the front sheet metal and every time I looked at the front lenses I'd get bumbed out. They looked so good new. I had built a polishing machine and have been doing metal for years. But never did plastic, I was afraid the high speed of the machine would melt the plastic. But I had to try. Click to view attachment
I was surprised. Takes a light touch. The metals I polish will remove skin they get so hot.
