I have a 2 gallon professional hand pump insecticide sprayer (B&G) which has developed a small pinhole
in an area not near a seam. The products used in the container are not corrosive, so I suspect that
there may have been a defect in the metal. What's the best way to close this pinhole? The max pressure
for the unit is about 30 psi. Thanks George Manth

I would silver braze it, using a torch with a soft flame.
