I know it is old school but I use it in my scenery. I have a question for the rest of the old farts here (maybe young ones also). I know to use glycerin on it to keep it from drying out, But do I mix it with water and how often should it be applied?

I found a reference in the May 1954 issue of MR indicating that it should be done about once a year (or sooner if you notice it drying out). MR recommended mixing it with water but did not give a ratio. I'll keep checking.

Update: In the Feb. 58 issue they recommend 1:1 ratio of water/glycerin.

Update #2: In the Nov. 89 issue a recommendation is made for 1 part glycerin to 4 parts alcohol.

Hope this helps.

Thanks Tom yes it does help.

Can it be permanently sealed?

In 1969, I started using Polyester fiber ( pillow stuffing, white ), and home made, ground and died foam rubber, for trees and bushes. I never was able to accept the concept of "re-treating" my scenery, every year.
That, and I was never really thrilled with the look of Lychen based scenery.
I did, in 1974, use Asparagus fern for the branches on some scratch built conifers, that looked really good.........I now, after 38 years, have some realistic "dead" pine trees.

I'm going to take that as a "No". 8-)
