I have some Unibond 800 that has been refrigerated for about a year and a half and am not sure if I should use it or not. If anybody can chime in on its shelf life that would be great. Also I am going to be getting some DAP weldwood Plastic Resin for a project on my house and would like to know if anybody has any experience using it on bows. If the Unibond is no good and I can use the Weldwood then great because I can get it locally.
