I have an'83 O'Day 28 with an iron keel on Georgian Bay (fresh water). I am going to strip the keel to bare metal and apply 2000/2001 before launch this season to hopefully hold back rust. At present there is only mild rust after each season. We have a product available at Canadian Tire called POR 15 Metal Prep. I have used Pettit's Metal Prep 6980 up to now but no Interlux epoxy before applying antifouling paint. I am looking for a product to apply to the bare keel to seal it from moisture before applying Interlux 2000/2001, then antifouling. Any suggestions of teqniques, products would be appreciated.
