Fixed some "unfixable" leaky wooden windows with this. It's a DIY super-caulker - a re-purposed cheap grease gun and a homemade fitting.
The grease gun has to be washed clean of oil before use.
It's only good for 1-2 uses before corrosion and caulk gum it up.
Be sure to wear eye protection and don't point it at
anything or anyone when under pressure in case the
needle blows out.
Materials Used:
- Caulk
- Small / cheap grease gun (well cleaned)
- Flex tube
- Brass fitting / drills / taps
- Inflation needle
