For me, jerkbaits are so finicky I never use Solarez to top coat them. It is too heavy, and affects the action, and the buoyancy, too much.
For any bait where weight is an issue, I use a concrete sealer, AC1315. Thin, strong, clear, UV protected (won't yellow over time), and fast.
I dip it outside with good ventilation(fumes), let it drip back into the container until it stops dripping, wipe off any excess drip at the bottom, wait 15 minutes, for it's solvent to flash off,and then hit with my hair dryer on low, to speed up the curing. I can handle it in an hour, and fish it the next day, although waiting another day lets it cure out completely.
There are other thin top coats, like urethanes and lacquers, but this is the one I've found works best for me.
