What's the difference between these two clear coats?

I've wondered this question myself.  So, I bought a bottle of each to test them.  In my opinion, the 1260 is thicker in the bottle than 1960.  It also seems to me that the 1260 is more "flat" than the 1960.  Then again, that could be due to mixing ratios or just because they're different batches.  Overall, I like the 1260 better.

I got an answer from Testors and they basically said there's no substantive difference except that the clearcoast 1960 is "higher grade" than the 1260 clearcoat.  I guess this is a parallel to comparing Model Masters flat black to regular Testors flat black.
