Great product, We use it almost exclusively for sealing gaskets. Or even just to hold them on during assembly. I love the brush in the cap. Each one of my techs have one on their box.
Correct, there is not a #3 labeled on the 4 oz bottle. We did confirm with the supplier that this is the correct #3H as they verified on the master case it came in and also cross referencing #80019 in which is labeled on the bottle.
