Well. this is a product (mostly?) sold in the U.K., so, as most of us here are in North America, few to none would have experience with the product!
Best check with folks on some DIY forum from there?
Wouldn't hurt to do some test of your own anyway.
Note that some epoxy products will expand or contract at a different rate than wood (I am told), but it won't matter unless you play outdoors (cue the Edge!).
Show us what your mod project look like. Who knows, someone may have done something similar, and may chime in.
