Wow, that's a very good piece of advice.
Working in plexiglass will darn sure be easier than glass and less costly if you make a mistake. I will call on my friend that owns a pizza restaurant, he has ovens large enough to place the glass inside. Scratches are not really a problem for me, the windows are almost always down, and I've only washed the car once since I bought it 42 years ago.
It pays to be on this forum.
Thank you so much,
Tom
