Proteus build thread (uber-tele)

[kinnikuman]

it's a polymerized linseed oil base, mixed with mineral spirits. So yeah, mineral spirits can be used for thinning (and that's exactly what Birchwood Casey told me when I asked them)

The info I'm looking for more is the thinning ratio that would be ideal for spraying, and whether or not Naphtha works better for this particular application.

Well do it by sight. mix in some and stir it, then pull the stirring stick out and watch it run off the end. It should run off easily/

Thats how pops does it and he has been doing it for almost 60 years.
