Thin-All Cement Thinner

Great thinner, just don’t spill it like I did

I've tried other thinners for thinning my head cement, but Waspi is the best. It thins all brands and doesn't have the thickening or color change issues I've experienced in the past. This is the true all-purpose head cement thinner.

Each time you open a jar of fly head cement, it starts to set, albeit very slowly. When I’m done tying for a few weeks or sometimes longer, a few drops or a splash will keep your head cement fluid and workable. I use it the squeeze bottle dropper too when needed.
