[SEL] Casting Filler

[Richard Fink Sr]

Curt you mention plaster for filler. here is a trick we used a time or two 
on autos that were rusted out bad and wanted a cheap fix. Get the patching 
plaster that is dry powder form and mix it with paint thinner what ever 
kind you are going to use fill the area sand off and walla good filler real 
cheap.
