i triple that. is very easy to get checkering too dark. another problem i had (and i checker after the stock is finished) is one stain i used on time ate tru-oil. i had a real mess. it wasn't pilkington but was another type brownells sells, maybe the USGI red stuff. try to mask off the checkering and not get the stain on the finished part of the stock any more than you have to. i know pilkingtons doesn't bother stock finishes. you might experiment on a test sample first.
