Alumilite dyes are not actually dyes. They are colorants made to be mixed into a plastic resin and cross linked with that resin when it cures. It is NOT advisable to use them in place of regular wood dyes. I am sure there are those out there who do it and will swear it works but there are just much better products for this application.
As for the cost issue brought up...Alumilite dyes are $5.75 per 1 oz bottle. Last time I checked, TransTint dyes were nearly $20 for a 2 oz bottle or $10 per oz!
