Can this product be used on plastic threads? The plastic threads are on a elbow fitting that will be inserted into a fuel pump.
I would think that would work, but test an area of the plastic to see if there is a negative reaction.

Bad packaging by Jamestown
Jamestown should put items like this in a separate plastic bag AND tape around the cap of the bottle.
While the product is very good the packaging was not. This is some very sticky stuff and despite the extra little flap of tape that JD put over the cap it still leaked all over the rest of the contents of my package. Either order this product alone or only with other products that can be wiped off with paint thinner or solvent.
