Greeting Wise Ones.
It seems I have a filling requirement, maybe? The project is a PB4 with Ash Body. The body timber is beautifully figured and the 'planks' all line up really well with no visible glue or filler so the Dingotone Nullarbor Ochre should be stunning! Started to sand the back (hand - P100) and a sort of de-lamination of the wood appeared, about 0.011m/m deep (pic #1). After a couple of hours sanding I have managed to chase the de-lamination along the body (pic #2) but this could go on for a lot longer! Already there is hand-sized hollow, not deep, but it's there. I will finish with Dingotone, so unlike a high gloss paint job the hollow shouldn't be too offensive.
Do I continue? Or do I stop now and fill? If I fill, what do I use?
