re: Lets Talk "oil finishes"

If you are talking about oil popping the grain, then it is a modified oil and not a true oil. Anything waterbased and is washable in water, contains some amount of water. If applying two different types of products, e.g. water based and natural, do some testing first as there may be compatibility issues that do not appear in the beginning. Modified tung oil contains mixtures of various products…and not necessarily natural products either, just depends on the manufacturer.

The smell or odor is not the only issue as a product may not necessarily smell but be still off gassing nasties. If the surface is to come in contact with food, one would need to ensure it is food safe especially if money is changing hands. If small children around, then one would need to be aware of any health issues that can arise with any odour from varnishes.
