Another solution to CA stains.
I assembled some ships boats kits using CA, and noted the CA stains. I am a total newbie. This was my first wooden model ship build. (USS Constitution- Mamoli, but the ships boats were purchased separately from AliExpress.)
In my ignorance, I decided that the solution to the CA stains was to paint the entire small boats with CA, using a paint brush, loading it in a puddle of CA, and brushing very quickly. The brush lasted about 2 minutes before it was unusable, and had to be discarded, so yes, I brushed very quickly. One brush per boat. On 6 boats I used 6 brushes. (cheap Chinese brushes, about $AUD1 each).
I was very satisfied with the result. See photos. These are all "after" images. The finish looked a bit like a satin varnish, and was reasonably homogenous. Even better, the small boats felt really solid and rigid. I accidentally dropped one on the hard floor, and it bounced, with no sign of any damage.
So, that will be my method of making and finishing small ships boats from now on, where I want to retain the unpainted wood look.
