The 'blue box' patch kit that Chuck is talking about is the Boxer patch kit. It is the best I have seen and should have no trouble patching a couple 3-4" holes. If you have other issues, you can still go ahead and repolace the liner. To give you an idea, my price for installing a new 16' X 32' liner, including 4 hours repair for the bottom, measuring, installing, balancing the water, new face plates, liner lock and 8,000 gallons of water is around $3,300 - $3,500 CAD. This does not include new foam or vermiculite.
