I have a bud who won't use the base/clear on old vehicles (he has like 12) because he says they are too glossy and I am inclined to agree. Paint has changed quite a bit since these things were painted. And on the other hand, I saw a very recent trail blazer (not more than 3-4 years old) with the finish coming off like crazy, and I have seen original nice paint on plenty of 60s era trucks. Kind of disgusting when you get down to it. Then again, paint regs are trying to reduce the good stuff which is pretty poisinous....
