[Wavery]

You could easily get away with a 3oz tube. This stuff adheres to almost any clean surface (except polyethylene plastic) and it's good for a multitude of repairs. It's slow drying so you have lots of working time.

You just have to be aware that it cleans up with mineral spirits (don't touch it with water). You can also put some mineral spirits on the end of your finger and smooth out the surface so that it blends in nicely and should be all but invisible. If you use a putty knife, coat it with mineral spirits too.

Larry, when you put it on the metal wafer, you can put some mineral spirits on your finger and work the stuff to match. Just don't get too much mineral spirits in there. Just remember that it dries almost pure white. The same color as the outside.

Also, be aware that once you open the tube and expose it to oxygen, the curing process starts. It's best to open the tube, apply as much as you need then quickly close the tube. The product in the tube may stay workable for several months if you reduce the exposure.
