I have been using this finish for over 15 years now. I like it. I have learned to use it and be aware of its limitations. I also have many other finishes to match different needs of restoration and have learned to use them as well.
The Pro Custom oil in a can is able to be made to last if you pull the nozzle and place it in a container of acetone immediately after use. I use a M16 brush to clean the face and the entry port of the nozzle when I remove it from the acetone. I have found it makes the can last much longer and I get to use the nozzles many times on many different cans. I have a collection of about 100 nozzles to rotate for the spay can method. If the nozzle doesn't spray or is a funny fan shape, I can just throw it away and get another to continue.
I also use the liquid for a different look. Thin the liquid with mineral spirits. Always shake the liquid mixture before usage. It goes on thinly and it dries well too.
I have used a Q-tip soaked in acetone to clean the top of the spray can and to remove the build up around the rubber seal at the top of the nozzle opening.
