another fiberglass repair question

[scosch]

I need to move an existing stanchion base on my Cape Dory to add a gate. That will leave 4 each 1/4 inch holes in the solid fiberlass deck. I know that serious repairs require a 1/12 taper, epoxy, fiberglass matt, etc. However in this case, is it safe to almost fill the hole with a resin (vinyl or polyester, non wax and non-epoxy as I heard gelcoat wont stick) and when dry, slightly overfill with a tinted gel-coat layer and then carefully scrape/sand/ polish?? Will it crack and fall out in a short time?? I want to do it right but dont want to do more than necessary.

Quote from west
Our customers' fiberglass repairs range from filling a minor screw hole to completely rebuilding the bottom of a boat that ran aground. In most cases, a final finish needs to be applied over the repair. If the repair is above the waterline, high-gloss paint or gelcoat are often used to reproduce the original appearance. If the repair is below the waterline, antifouling paint is most often applied over the repaired area. However, customers often want to restore the original gelcoat finish to below-waterline repairs where the boat is kept in the water and no antifouling paint is applied. These customers are concerned about the gelcoat's long term ability to adhere to the area repaired with epoxy. There are good reasons for this concern, but if you understand the materials involved and follow recommended repair procedures, you can successfully apply a gelcoat finish to a boat bottom repaired with WEST SYSTEM epoxy.

fill with thickened epoxy. gelcoat will stick to properly prepared epoxy resin.

Please never even of fiberglass mat and epoxy at the same time. They don't work at all together.
