GFlex Expands more than regular epoxy?
I routed and filled my topside plank seams with epoxy and filler. (1950 Chris Craft Cruiser) On a couple of seams I used GFlex as an experiment thinking it might last longer than regular epoxy. I've noticed in the hot weather that the GFlex filled seams show through the paint very slightly as if the G-Flex expanded. I didn't think about increased flexibility equating to greater expansion when heated. Anyone notice this or can confirm this is what is going on? It is very slight and doesn't bother me (much). But, if the regular epoxy holds up as well, or nearly so, I don't think I will use the GFlex for this job again.
I'm not looking for commentary on whether it was a good idea to route and fill my topside seams but if you must . . .
