I've almost arrived at the sanding stage on my cedar strip/fg 16 footer and quickly realizing that there's going to be many gaps which will need to be filled. Most the articles I've read say to use epoxy mixed with wood flour or sawdust to fill the gaps but I'm a bit hesitant to use something as hard as epoxy on something as soft as cedar. Has anyone used the fillers sold by Lepages or other companies which are used to fill nail holes ? These fillers sand very easily and are available in several shades. The only thing I'm wondering about is how they would react to the resin.
