In the few times I have used dope, and it's been literally 5+ years , i didn't use any castor oil to prevent any shrinkage.

Thank you. I don't know what polyacrylic is. Is it a modern substitute for butyrate and nitrate dopes for use on model airplane tissue and/or silkspan wing & fuselage coverings, or is it a bonding agent related to cyanoacrylate (CA)? Its waterproofing trait sounds very useful, especially for flying on dew-dampened grass fields.
