I use a lot of these glues. They’re ideal for all manner of model making jobs. But there’s a problem with them.
Their chief benefit is this Revell Contacta glues, apart from their quick setting time and the strong bond for plastic models, wargaming models etc, is that they have a needle applicator dispenser that allows the glue to be precisely placed.
The problem is that between uses the glue remaining in the needle tube often sets hard, blocking the tube and rendering it useless. Even with the cap on, it often glues up.
This is just one of those problems I’ve lived with. The packs aren’t expensive so it isn’t a massive problem but it is mightly frustrating.
I’d just assumed everyone else suffered in silence like me.
But it turns out there’s an easy solution.
Just heat the needle tip tube slightly, over a lighter or candle flame for a little while. This loses up the glue. Then just poke some wire through to clear it.
Hey presto, long life glue.
- Health and safety notice: keep the naked flame away from the fluid glue and the plastic pot, for obvious reasons. Also, do this in a well ventilated or open area.
