Question Bookcase issues

We had bookcases built out of cherry. They are presently unfinished and built in bookcases. We are considering using tung oil without any prestaining as a finish. There are a few areas with sap wood, but we have concluded that blending the color will be extremely difficult.

The remaining concern is whether the tung oil might damage the books in any way in the future. After the tung oil dries and sets up, is it "permanently dry" or are our concerns at all justified?

you should not have a problem as long as you allow the oil to completly
dry. always always be very carefull with the rags after you are finished
with each coat of oil. that includes all oils, watco or whatever. they
will spontaniously combust on you if you do not take them out side and
spread them flat with weight to dry. check this site out for other responses.

Once the tung oil dries, it will stay that way. Tung oil has long been a finish for wood. It is straightforward to apply and simple to repair or refresh, if needed.

Trying to blend the color of sapwood can be challenging. Trying to blend sapwood to match the rest is why one would stain cherry with cherry. The variations of sapwood and heartwood are part of the nature of wood. The natural product gives natural result which are not the uniformity that many expect.

Use 100% pure tung oil, stay away from mixes with other products. There are many blended products out there, but don't perform as well as the pure product.

Hope this helps.

Another option would be to have a refinisher come in and tone the light spots with the darker after you have a finish on it. They have aresoles for this exact situation. No, it's not like going to the store and buying stain in a can. There is an art form to using these aresole cans and blending. the color is misted on from a certain distance. It's not a matter of doing like they do on the home improvement shows and use the aresole cans with their fingers pressed all the way down.
