I have not used DNA during finishing but I do have a lot of isopropyl alcohol. Will it work in the same as DNA?
Depends on what percentage the isopropyl is and what you are using it for in finishing.
Ordinary rubbing alcohol has a high water content - about 30% I believe. Generally not good for cleaning wood blanks as a finishing prep or sanding dust cleaner.
DNA is generally only about 3% water. I buy it by the gallon & keep the can sealed except when refilling my squeeze bottles to keep it from absorbing water. I also keep my squeeze bottles capped except when squirting some DNA onto a paper towel.
Alcohol attracts moisture...moisture in the air readily dissolves into alcohol of either kind. As soon as the lid is removed water enters. I do not use alcohol on any turned items. Lacquer thinner or acetone are my choice...they evaporate very quickly. One method of drying wood is to submerge the wood in a container of alcohol and water moves from the wood into the alcohol...at least that is what I understand about the process. I'm sure (and it is OK) I will be corrected if wrong.
Do a good turn daily!
