A few drops of castor oil is refered to as "plastciser" and yes, it will make dope more shiney, but dries slower and you must not add too much.. I think it was two eye drops per quart or such. You can buy platiciser already made up, from Dave Brown Products.


DO NOT USE OLIVE OIL.  Save that along with vinegar for your Italian salads.

Plasticizer in color dope may make it flow out flatter.  If you're going to sand, clearcoat, sand and polish, then it's not going to make any difference.  Or, if you go overboard, you'll have a softer surface that's harder to get to really polish up.

  If you are going to try castor oil, use medicinal castor oil. It is processed to a much more pure form, and is clear. Dave Brown products sells their product called "Flex-All" and Windy used it in his finishes. I really believe that is all Flex-All is, medicinal castor oil. it looks about the same , and I did a small taste test and it tasted the same to me.. You do not need much, a cap full to a guart of thinned dope I think, and when I use Flex-All, I also use fish eye killer from the auto paint store and had no issues.
