Carpe Diem! (Seize the Day!)

Model Filler and Finish Compatibility Matrix

I am not aware of the origin of this matrix, but it is a very useful tool for determining whether certain filler materials and finish chemistries are compatible or, equally important, incompatible. It was included in the July 2012 edition of the Bean Hill Flyers control-line club newsletter. This might save somebody the grief and angst from applying a finish over a base that will cause it to bubble, peel, blister, or not ever dry.

One thing this chart does not indicate is that you can apply butyrate dope over nitrate dope, but you CANNOT apply nitrate dope over butyrate dope. There might be other instances of one-way compatibilities, but if you are not sure, do a test first or avoid the deadly combination altogether.

Please let me know if you have an experience contrary to this chart.

 

White = Compatible

Red = NOT Compatible
