Re: [CBQ] Rapido SW1200

The funny thing is that even if someone did find a sample of the prototype 
applied to an object that had not been exposed to light, it would probably be 
more yellow than when originally applied.  Alkyd resins such as the paints used 
back then will yellow in the absence of UV light to some degree.  The resins 
can be formulated differently to reduce this but you will make the dried film 
more brittle and prone to chip and crack, so paint manufacturers had to balance 
hardness an elasticity when formulating those paints back them just like they 
still do with modern coatings.

It’s not like you could call DuPont and order a batch of that paint these days, 
lead based pigments and resins used back then aren’t available so any formulas 
that may still exist are kind of useless 70-80 years after the fact without the 
raw materials.

Just my $0.02 opinion.
