: I just did the filling on the hull of my kayak, and was wondering if any
: excess will show up a different color once it is fiberglassed? Should I
: sand it all away? Is it okay to leave it there?

: Thanks

Wet it, the colors when wet will be very similar to the colors once glassed.

Generally it's hard to get filler to match exactly, so less is better. Though truthfully the only one that'll see it is you, unless you tell someone else what to look for.
