I am an avid canoer, have built and repaired fiberglass and wood canoes for 40 years. the boat in our picture is a wood strip canoe that we built. I have a lot of experience with patching/repairing fiberglass.
The fiberglass repair kits are the way to go. West Systems makes a very nice kit that has everything you need. Here is a source

I don't know how many dents you need to repair, so the volume of materials will have to be decided. Buy one kit, follow the instructions carefully and it will work. Then you can determine if that is the right thing to do.
Wash the repair area well. Mask around the repair area with a good quality painters tape and newspaper to stop spills or runs. Sand the area around the repair to lightly scuff it and give it a small amount of texture. sand about 1" beyond the repair area. clean the area sparingly with acetone. fill the dent with epoxy putty until it is level. after it is dry, apply the fiberglass patch. Generally there are 2 tubes-the resin and the hardner. mix them together per the instructions, brush a coat lightly on the pod skin and saturate the fiberglass repair patch. It works best to work on waxed paper so things don't stick. apply the patch and work out any creases or air bubbles. make it as smooth as possible. then cover the area with tightly stretched saran rap. again smooth everything and then tape the edges to keep the saran tight. the saran texture is your final finish when it dries. it pays to smooth it as much as possible. after the epoxy dries, pull off the tape and saran. you can now lightly sand the patch for final smoothness.
Most marine supply house will sell the West system repair kits. they usually also have small bottles of white color that can be added to the epoxy resin. read and follow the Directions
good luck
