The Pastry Bag - Beyond the Galley

We had to repair a fiberglass water tank, and wanted a syringe to squirt the repair fiberglass goop into the crack we needed to seal. Syringes are handy for that sort of thing, but we were out of stock, and the nearest pharmacy where we might get one was a couple of hours round trip – time we didn’t want to spend acquiring one.

Our solution was to use a heavy duty zip lock bag as a sort of ‘pastry bag’, mixing our fiberglass paste in the bag and cutting a nick off of one corner, allowing us to squeeze the mixture out the little nick into the cracks that needed filling, with good control.

As a bonus, mixing the fiberglass resin, hardener and filler in the bag was easy and there was less smell as the resins were contained!
