Well, I ordered a bunch of different stuff from
Stew-Mac to experiment with, and I found this article on a Telecaster site.. "Well here's where it gets tricky. We know what Leo's own costing analysis specified for materials and processes (shown below) but that was a single moment in time and obviously changed. Also, product descriptions can be deceiving. What one manufacturer refers to as "sealer" another might call "stain" and so on. Further complicating it is that 1950s product nomenclature differs from today's. But here's the rundown briefly (this information is in The Blackguard Book and Dan Erlewine's Guitar Refinishing book by the way).
1.) Spray primer and check over........3 min.
2.) Fill with filer and rub off.......20 min.
3.) Stain and check over..........5 min.
4.) Spray Sealer - 10 in 30 min.......3 min.
5.) Hard Sand............15 min.
6.) Spray Gloss - 10 in 50 min........5 min
7.) Polish (all good bodies).........15 min.
You will notice that there is no reference to spraying a pigmented blonde shader coat. That's because the "stain" listed in step # 3 was actually a blonde shader coat, Harper's # L-804. We know that from researching the product numbers. It was mixed with 40% primer, # 1362. So a little investigative work is needed to understand the steps outlined above. But one thing is clear, they didn't waste a lot of time painting these things!
Anyway, there are actually more questions left then there are answers to, but hopefully this gives you some idea of the process. What we can say with certainty is there was definitely a white blocking "stain" of some sort applied and possibly to the raw wood. It was likely brushed at first, then sprayed. Then the bodies were sealed again, pore filled, and a pigmented shader coat was sprayed (the opacity and color varied quite a lot) followed by clear. So if you want to recreate an authentic looking blonde those are the steps you need to follow. You can achive an "aged" look by tinting your final clear coats to whatever look you are after. "
I have a keen sense of adventure, a full can of stripper, and a box full of stains,tints,pigments,fillers,and lacquers. I've been studying the pictures in the 51-54 Precision book, and I think I got this..! I'll be back home in 2 days...Pictures to follow after the fumes clear out...
