We should have a ‘dull-off’ between this and

to see the advantages and disadvantages of each for model-railroading purposes.
I might have some issue with the 6 - 12 month substrate drying time[:-^]
This varnish dries to a flat, non-glossy finish, suitable for oil, alkyd, and acrylic paintings. Paintings must be thoroughly dry (at least 6–12 months) prior to application.
There are certainly many clear finishes out there. I’m familiar with Dullcote, both rattle can and bottled as well as the products offered from Scalecoat.
Another forum suggested Rustoleum Dead Flat. I thought that stuff was awful for any kind of model work [N]
The Krylon product previously mentioned was praised for its UV resistant properties. Something I’ll file away for future use in a garden railroad setting.
Thank You, Ed
I got it from Above Ground art supplies… they’re local to Toronto, but I expect the stuff or similar would be available at most real artist supply stores (though not at the likes of Michael’s, last I checked).
Re: the 6 to 12 month substrate drying, I expect that refers to oil paintings, where artists slather on very thick layers of oil paint; not relevant to us.
