Took a chance on a "Fatboy" I came across. It arrived today and it is even uglier than the picture shows
Paided more than I wanted to but with the prices on these going up I thought I would take a chance. I'll clean it up later and post a pic when I'm done.
I used to smear hand GOOP on the real ugly ones and let it sit 24 hrs. The GOOP goes on white but turns clear and runs off over night taking the crud with it. Then dish soap and a toothbrush. Put on you sun glasses before turning up the lights cause it with twinkle.
A very light abrasive polish like Peek or Maas applied with a toothbrush will bring that up a treat. Just work it in gently with an old toothbrush & leave for a few minutes, then buff it off with a microfibre cloth.
Go gently & it should come up like new.
