Tung oli

[Badger]

   I agree Jeff, never sand the final coat, good suggestion with that pumice and veg oil.

  400 grit is about the finest you need to go for finishing and sanding between coats even 320 will work just fine.

I'll try using those grits, thanks for pointing this out.

The tung oil i used doesn't dry. I aplied it 3 days ago and wiped it down after one hour. What could go wrong?

[PatM]

Lack of patience.  They polymerize over time.  Was it raw oil? 

[maitus]

Don't know. There is written "pure tung oil". No idea is it raw boiled or what ever ......4. day and it doesn't dry regardless i rub this bow every day with clean rag. I should get true oil. No wish to try tung oil anymore. The question is how will the true oil act after the tung oil?

[PatM]

Chances are it's just raw tung oil. That can take weeks.

[maitus]

OMG ....! But there stays that next coat must be applied on the next day.

[PatM]

Sure.  Many say you can still apply a thin wiped on and off coat each day but it takes time to fully cure the whole thing.

the temperature and humidity matter too.  Right now I am finishing a bow with tung oil in a cold-ish garage, and it is taking noticeably longer than during the summer.  I have been bringing the piece in at nights to warm it up.

Mine is hanging in my livingroom.
