DBU is now DBC and the DRR reactive reducer is gone. Now you add DX57 when needed and use DT reducer. But yes it pretty much smells like remembered.
Lacquer is the smell that jumps out at me when I sand into a layer of 80-S or DZ-7, or Duracryl or Lucite.
Yes I remember Ditzler. From age 20-25 I was a paint mixer with no less than 10 paint lines stirring. PPG, DuPont, Sikkens, Sunbelt and all variants of each. If I had a penny for every pint of Lucite I made to match a gas cap I'd still be rich. Used to mix 100 gallon lots of Imron 1 gallon at a time on 5 scales at once for KCS railroad. My paint history runs deep.
But I swear, along the way very few people have wanted SS, even back then. Acrylic urethane was new and king of quality then and still is now. I have always pushed for quality in my ventures. Thats why I cut my teeth on polyurethane on my own car. It was best. PPG's Imron equivalent.
Modern basecoat is still acrylic lacquer. I haven't heard Centari in a long time but have heard Starthane in recent times. Watch out for expired product if you mess with that stuff. AE with drier in it attacks the can after so long. End ramble
