No success to report on inter- strip gap filling. So far I have tried redwood dust in epoxy - comes up too glassy and grainy and also murder to sand. The other night I tried mixing dust with plastic wood but it just wouldn't mix in. The plastic wood gives an ideal fill but it's too blonde. How to bring the color down is the problem. Maybe I'll try mixing it with some Minwax stain.
Any suggestions on this problem would be welcome. JJ.
