I use the Hobbylite filler myself, and I absolutely swear by it. But,
like most finishing materials, it requires a bit of practice to use well.
For the grooves, you apply the Hobbylite along the groove, not across
it. The stuff is self-adhesive enough so that it will 'roll' out of the
groove as your spatula/finger applies it crosswise. It helps if it's a bit
thin, too; I dip my finger in a bit of water, get some filler on it, and
spread it on. Directly from the jar is far too thick to work properly.
Same applies for the fins. Be fairly generous, and make it a bit thin,
a bit thinner than instant pudding. Cover the whole fin, wait for it to
harden, and then sand most of it off - but don't use wet sandpaper, because
it will dissolve the filler and you'll have to start all over again.
Most of what you apply will end up on the floor, of course, but that's
filler for you.
And I noticed today that my first jar of Hobbylite is finally almost
empty. Time for another trip to the hobby store, if I can get hold of a car
