What's in the 407 and the 410? I know WEST has some fillers with cotton
fiber in them, others have plastic, but I can't remember which is which. My
favorite mix for hole filling is 75% silica, 25% microballoons (phenolic).
A separate post talked about my fill it, cure it, SurForm it way of making a
smooth fill with fewer passes, but here's a picture of how it turns out:

proposed a theory
......and in reply I say!:
remove ns from my header address to reply via email

there is/was no wood "plugs" - there's 3/4" marine ply that's been in
there for 26 years - and why would a ring of 6 holes expand?

turns out West says their 410 additive can expand - they now say use
only 407.

OK. I and one other posted saying that the sanding may be the problem.
OOI, can we hear back what happens with the non-expanding filler?

We may be wrong, but we tried to help.....
