Is there an equivalent to squadron putty to fill small holes in plastic but black in color?    Bob V.

I am not aware of a commercial product.

You might try dissolving black styrene in MEK or in any of the liquid cements for styrene, until you get a putty constancy. This will bond well to styrene but is likely to shrink severely. Adding an inert filler to to this should reduce the shrinkage. I would try lampblack, black chalk dust, or charcoal dust mixed into the above, or into a clear commercial bodied styrene cement, adjusting viscosity with MEK or a liquid styrene cement.

This is essentially what the squadron and similar putties are: a fine inert filler mixed with a plastic binder and enough solvent to soften the mix. The older products which were originally intended for wooden model airplane construction used acetate plastic, as did Ambroid's model cement, and neither binds well to styrene. Modern putties for use with styrene are more compatible, being made with styrene but i find them a little short of binder..

Tamiya makes body filler, but not sure of the colors.

Get some Kadee black spues and grind them up, or sand them into a pile.  Add a trace of liquid glue so its a paste and fill away.  Repeat until satisified.  It may take a week to dry hard, then sand and gloss

The other thing is that not all samples of black look the same. If a true match is the quest you may be looking for a suitable paint not filler.
