Steve - depending on how much woodworking that you do that
ends up being stained, there is one product that "helps" to identify
where any residual glue may be hiding that could ruin your project.
it is a fluorescent glue that glows under a blacklight.
I have never used it as I do not do a lot of stained projects.
I know of a guy on another forum that swears by it as it helps him
turn out a better project and shortens the cleanup time.
the last I checked, it was only available in one gallon containers.
even tho the small hobby bottle is shown on their website, it is not available.
you can decant it into smaller bottles and keep them in the fridge to extend shelf life.
this is your call - as to if it is worth the investment or not.
TITEBOND II FLUORESCENT WOOD GLUE
Titebond II Fluorescent can help any woodworker achieve professional-looking results.
It provides a strong initial tack and fast speed of set to reduce clamp time.
It also develops bonds stronger than wood, offers excellent sandability and is unaffected
by finishes. Titebond II Fluorescent contains a dye that, when viewed under a blacklight,
enables woodworkers to inspect the glue line and assist in the cleanup process.
It is ideal for most porous materials, is easy to use and cleans up with water.
