Just invested in a tube of Indasa Car Body Sealer
so that I can seal the deep seam above where the bonnet hinge meets the body, just under the cabin air vent.
What I want to know is: will the sealant go hard in the tube if I don't use it all in one go? I only need to use about 1/10th of the tube's contents for this job. The contents are highly flammable, so I'm guessing it won't keep if the seal is broken, but I'd appreciate anyone's advice and experience with this type of product.
