yea ive done a few layers so far, sanding a little in between to get the layer before enev then adding more to fill in any gaps.since titebond shrinks i add a thin layer of it under the new filler too, then ive been laying a piece of sandwich bag over it and compressing it. i figure itll help just like clamping any other pieces of wood together would. ive done this, and then soaked the patch with CA on other stuff, and even used TBIII and brown paper on rounded stuff,sanding it even after its all dry. end product is as strong if not stronger than when starting out.
