Reply to: Inter 20 hull repair

Message body

[quote=arch]ch,
for a filler material to fill in large dimples or depressions, i just used this 'paste' 100695 on my I20 hulls to fair them.  it's a clear, slightly greenish color they call 'neutral' and they suggest adding color, in your case 'white' to match the hulls.  this can be applied with a wide drywall trowel to span the repair.  you don't want to get it any thicker than you need or outside the depression cause it remains kind of sticky and i've had trouble with it plugging up my sandpaper so it has to be trashed.  (i know i mixed the hardener correctly.)  they say you can sand it but i would just fill the depression and then top it with the gelcoat 105670, a one-step gelcoat that doesn't need a covering to cure.

something else i've seen is adding a powder filler material to gelcoat to make a paste.  do a search on gelcoat paste on the internet and you'll find different powders you can add to make it thicker.

i would stay away from bondo cause it can absorb moisture.  and epoxy as a sub-layer may keep your gelcoat from curing.  i found this to be the case on a daggerboard i repaired and wound up having to remove the gelcoat with acetone then completely dig out the epoxy.  but some comments say it's ok over epoxy.

i've just found this all works well for me.
