  1. This is what my Z looked like in 2006, when it was my younger son's driver. It's too bad I couldn't have garaged it to keep it from turning to crap. It's currently in primer, and my current plan is to paint it Mustang Grabber Blue, with all the chrome bits powder-coated black.
  2. yep. her feedback is low b/c she has only sold like a 3 things in the last year and 1 was a negative. Looks like the rest of seller history is solid.
  3. The clear coats solved the problem with metal flakes - but created another problem - over a short period of time in hotter sun regions especially - the clear coats started to crack - at first it looked like fine scratches in the paint, then got worse over time as the clear coats increased “grazing” until they started to flake off. The problem as explained by the BMW Factory Tech's - was UV light passed though the clear coats and heated up the color coat under them. The difference in the coefficient of expansion of the two coatings caused the clear coats to crack as the color coat expand more rapidly under them. In 1972 BMW and VW had such problems that new cars sitting in stock were crazing before even being sold. I worked for a BMW/DATSUN dealer then. Lots of customers with BMW’s had their cars stripped and repainted - under extended factory warranty - cars up to 3 years old were covered. The solution at the time - was to mix a small amount of color with the first application of clear coat - then put a second clear coat over that. That made the heat transfer between the color coat and the final clear coat more slowly and evenly… Do agree that by the 80’s newer paints solved the problem by more closely matching the coefficient of expansion of the two different materials.
  4. I can't find anything definitive about what Datsun/Nissan was doing but my understanding was that clear coats weren't used in high volume until the 80's and mostly on high end cars. I remember guys getting clear coats on their hot rods in the late 70's but that was a custom paint job. This article suggests that the late 70's/80's was when they really came in to high usage. https://www.paint.org/coatingstech-magazine/articles/brief-history-automotive-coatings-technology/ "As previously discussed, thermoplastic acrylic lacquer automotive coatings, given their excellent appearance, were the major automotive topcoat used in the 1950-70s. However, these lacquer topcoats did have one significant drawback: they had weak exterior durability. After about one to two years’ exposure, the coatings would begin to degrade, and aggressive waxing was needed to “bring back the shine” of these systems. By the 1980s, the automotive manufacturers were requesting better durability for automotive topcoats, as consumers were now expecting their cars to last at least five years, and they wanted the car to continue to look like it did when they first saw it in the showroom. " This Toyota page shows a clear on a solid as a one step/one bake process in 1973 but no clear top coat again until 1990. https://www.toyota-global.com/company/history_of_toyota/75years/data/automotive_business/products_technology/technology_development/materials/painting/index.html
  5. As far as I know - all metallic automotive paints in the late 60's and early 70's were clear coated.(I worked for Datsun/BMW and VW in the early 70's). My 1970 Silver 240Z was clear coated from the factory. The reason was that some of the metal flakes mixed with the paint being sprayed - did wind up at or near the surface skin coat of the paint. Any polishing/waxing or compounding at that point would have resulted in the metal flakes sticking above the surface. So metallic paints on the 240Z were clear coated. FWIW Carl
  6. All tuned up. Fuel pump pickup today, I'll report back after install.
  7. For a 73, that is correct for the choke cables.
  8. The yellow arrows confuse me! I'm just a primitive cave man...
  9. Should bring strong money. https://bringatrailer.com/listing/1973-datsun-240z-152/
  10. This is awesome... I don't have to even get involved!!
  11. May 2013 newspaper, are you a hoarder with a house full of cats?
