I'm new to this forum but have been using SPI products for 5 years or so. I have only done restoration work on the side since the early 80s and have only painted a dozen cars or so but have always used polyurethane clears. Mostly PPG 2002 and what ever the older version was 2001 maybe. My last project was a 70 Chevelle and I used all SPI products except for the polyester primer which was PPG Vibrance line. I used Universal Clear and the image reflection is near perfect but I wouldn't say the car is necessarily "Glossy". My question is Euro 2020 polished to the same level glossier than Universal? Also is there any advantage to shooting Euro unreduced?
