model builders
it turns out my Guillow's Goldwing needs sealing.
Guillow's stays out of the dope recommendations, they just say
use Elmer's glue and water.
found this Sig nitrate dope that looks pretty good, here are their tips on it.
Better adhesion to most structures and coverings than butyrate dope
Controlled shrinkage - Nitrate dope shrinks only a moderate amount compared to butyrate
Helps eliminate warps and dope "blisters" at sharp 90O corners
Higher solid content than butyrate dope for faster filling
Compatible with most model paints - Nitrate dope is often used to seal the bare model surfaces and provides a good base for finishing with butyrate dope, enamel, or epoxy paints
Ideal for use alone on light free-flight rubber models where fuel proofing is not necessary.
the last line sort of clinches the deal for me.
have a nice day!
