I like cats and we have one, so no problem there! (For the record, I like dogs too, and in general most animals. Just don't ask me about mice...)
I appreciate the offer - maybe a future "HawkRod Power tour"?!? Stopping at your place will really highlight the power!
When I restored my 70 Road Runner I had some scratches in the glass as well. I was told that if you can catch the scratch with your fingernail then you can't successfully polish the scratch out. I found that to be true, although after polishing all of my glass I found the big scratches were less noticeable. I hope your scratches are small and you have good results!
