I've filled a few holes with help from Warthog and others here when I moved my all around light and put the bigger tabs on. Anyway, you can buy the off white gel coat from your local dealer to top off the repairs. Gel Coat is easy to work with as after it sets up, you can wet sand it with a very find grit. I saw your project and if you are going to fill holes that you can get to the back or bottom side of, you can put some tape across the hole until the resin mixture sets up? I'm sure other, more experienced guys on here will chime in and help. See below for some material ideas. YouTube is also a good source for how to on working with Gel Coat etc..

The easiest fix is to put some sealer and a bolt in the hole. The bolt head is very unobtrusive...
