Fiberglass will eat a planer blade in no time and you have little control of
how much gets removed. The best way to remove a lot of glass is with an
angle grinder and a 40 grit flap wheel. The flat kind that looks more like
a regular grinding wheel. You can dig into the cracks and feather the
edges very easily.

I have a canoe that I am reworking. It's got a few holes in it and the
keel board has chunks of fiberglass missing and deep cracks in the
resin. Has anyone used a power planer on fiberglass as a way of
removing it? Did it ruin your planer? I should remove the cracked
resin, shouldn't I? It's falling off in squarish chunks and doesn't
look very safe. Also, on one side the outer layer of glass is
seperating from the hull and I peeled most of it off. It's cool to add
one layer of just resin, then a layer of glass fabric and then a
gelcoat to make it smooth, right? I mean. that should be ok for a
canoe that won't be under power other than paddles. Shouldn't it?
I don't want to get a few miles from the car downstream this summer
and have it come apart on me. If I cover it good like I described it
won't matter what the underlying hull is like as long as it's strong,
or is that line of thinking going to get me soaked?

But will the resin ruin my planer if I use it to remove all the old
resin off of the keel board that runs down the center. And that gets a
layer of fiberglass mat when I reglass it so rocks won't ruin it, if I
remember right. Hope I do.

Am I fixing to have a bad boating day when I get finished with this
thing?
