I used Elmer's glue 70/30 with water as per the building leaflet that came with this Guillows 905 P-51. In the past I was a Pactra dope devotee, but I can't afford it now and still wanted to do a plane. So I gave the Elmer's a try. Not too bad really, considering the cost. Plus, all my older planes I had built in the early 90's with Pactra were all splitting and tearing. It seems the Pactra dope kept shrinking and shrinking the skin over the years till it split itself all up. It looks like my Pactra dope days are over.

I have used nitrate dope over Elmers glue, and then used rattle cans, with zero issues. But not exactly your situation. It's easy enough to do a test piece, on some scrap, do that. I put a layer of Elmers over foam fillets, so then I can cover, and paint, without dissolving the foam. I just recently used clear Krylon on tissue, and really liked the results, (very very light coats). I am just curious, how did you end up on the silkspan/elmers/paint road? Water based furniture sanding sealer keeps popping up in my head. Applies and sands easily, and accepts rattle cans. I use it on my RC electric wood sheeted fuselages. Do a test piece of your Elmers idea, let us know. When I use silkspan, and want to paint, I still stick with nitrate, and then water based or rattle can finishing. From one silkspan and paint builder, to another, Welcome. I love the ability of getting the exact color, and sheen I want. And also the ability to mask off and paint stripes, or whatever other details I want. Please post pictures of your project. From my experience, Elmers glue and Krylon, just guessing, it will stick. I would still primer it, or use paint/primer combo.

You might have problems with the paint pealing up from the surface.  I'm not sure what the effect of the water based paints would do but they might work.  I've not used this before so I'm just guessing. 
Ok modelers...anyone out there had experience with this and what are your suggestions?

Krylon over Elmers Glue?

This is not my first stick and silkspan build, but the first time I went with thinned-down Elmers glue to "dope" over my skinning job. Actually it looks nice, but you better not touch the plane with wet fingers. It seems to re-dissolve the glue and makes fingerprints and dull spots. But that's off-topic for the title of the thread. I know I can use krylon spray paint over a butyrate dope and tissue job, but what will happen if spray paint over an Elmers glue and tissue job? Thank you.
