Fibreglassing Question

-Suggest making up an epoxy putty - Bondo absorbs water and may very likely
cause either delamination (if you glass over it)- or it will just fall off
after a time. Lacking microspheres, you can use wood dust, or even flour (not
self-rising) as a thickening agent ... although if you do use flour and it is
exposed - bugs will eat it.
