Ok, here's the REAL scoop on Elmers GluColors...
I e-mailed Elmers asking where I could find GluColors and here's their reply:
"Thank you for contacting us regarding Elmer's Glue products.
Elmer's GluColors is a product line that has been discontinued. I feel this is the reason why the online hobby shop is only offering the red color. The product line was
discontinued 7-8 years ago and at best this product would be 7-8 years old, which is well past the 2 year shelf life expediency."
So, it looks like I use additives to regular ol' Elmers.
All out of Snakes and Nape, switching to guns...
