Vito,
Yellow sinkers are to moch corn. With most of the sinker bouncing in the mud and out of sight, a part of the sinker will be above the mud and insight.
The plastic dip is going to be way to thick for jigs with details. It will cover it right up.
I am going to hit up a couple more 1's today aswell as my fillet knives, plyers, and other things...
Spray painting the sinkers is ehhh.. Not good enough for my boat.. I went as far as putting 2 dips on each sinker..
