I remembered a post by fishbones a long time ago, in which he used a microwave to apply glitter to soft plastics..
So I decided to use a lighter and try it out myself:
Skippyfish.. now has an "American Shad" type pattern
Kalin's Smoke gold n pepper, Now has a "Golden shiner" look
Old fluke, now revitalized with a pearlescent sheen
Plain white and silver, great for overcast
"Candied" crawbug
Kalin's Pumpkin salt n pepper, "candied"
White with gold hologram flake..
Kalin's Watermelonseed "Candied"..
These should really work well with halibut..
As a bonus, when a fish bites them, it will dislodge a cloud of "scales", giving you a second chance for a strike.
