Subject: Pietenpol-List: dye for dopeGuys, (and gals?) I'm using the old fashioned butyrate dope system over my ceconite. I'm about ready to start spraying. The first coat must be nitrate dope as butyrate doesn't adhere to ceconite, whereas nitrate does. The problem is the only non tautening nitrate I could find was untinted, and I'd like a little tint to help with even coverage. Does anyone have any suggestions as to what might work as a tint? is there any reason a little rit dye or food coloring wouldn't? (there's water in there)thanks,Douwe________________________________________________________________________________

Subject: Re: Pietenpol-List: dye for dopeDouwe,Since you have to add AL paste/powder to the final coats of the dope for UV protection, I think I'd add only a very small amount of this approved and necessary "pigment" and forget about experimenting with various dyes that you have no idea if they'll co-react with the dope thus changing the dope's properties and/or worse make the dope brittle. You could very easily add very small amounts in varying quantities per coat of the already needed AL paste. To see if your coverage is complete.Gordon ----- Original Message -----
