Need some advice...I am going to attempt to fill a 2" diameter machined hole that the previous owner made in the deck. The deck is fiberglass with wood core. I have never worked with fiberglass but I have been researching procedures and I think I am ready to take this on. I found this kit at Ace Hardware and wanted to get an experienced opinion about it... http://www.acehardware.com/product/index.jsp?productId=1381701&kw=marine+fiberglass&origkw=marine+fiberglass&searchId=54869100543 since it's such a small job I don't want to spend money on excess materials. I figured I would also use a wood core cut to the diameter of the hole and glass it over. Do you think this is a decent option?
