These are the first lures I have made sience finding this web site. I made a few trolling plugs a couple years ago that looked OK and had good swimming action. But after using them for a vary short time the finish would crack then the wood would split. A few weeks ago I came across this site and figured out what I was doing wrong....everything!!!! They are made of red oak, sealed with Devcon 2 ton, painted with createx and clear coated with Devcon 2 ton.
