Topic tags/keywords: question pine finishing traditional

I’m building a dutch tool chest out of douglas fir and one of the sides has this pocket of dried sap. It’s dry enough that I was able to plane it just fine with my No. 4. I was planning on putting a coat of 2# cut of shellac then using a latex based paint.

Do you think there will be any issues down the road? I would hate for it to warm up and the paint starts to bubble.

I’m looking at either leaving it and finishing as described or cutting it out and patching.

Thanks for any input you can provide.

the “best” way would be to cut it out and put in a “Dutchman” of the same
grain pattern. then prime & paint as normal.
I would not use epoxy as it is much harder than the surrounding tissue and
will leave the proverbial grave outline.
but, I very often dig it out and slap in some Bondo autobody filler too.
just depends on the project and time of day.
if the dutchman patch did not fit perfectly, I would still use Bondo to fill any gaps.
(under paint that is. with a stain or clear finish, you have to be a little more imaginative).

For a pocket that size, removal would be best. I’ve used Bondo in the past for such things and it’s always worked well…but i recently tried this JB Weld Wood Restore and I prefer it to the bondo.

I would just make another piece. It is only Douglas Fir, after all, not some high priced exotic species.
