Plastic Filler

[John Clutch]

I would like to add more detail to the engine block but some mods will require cutting through the wall. Is there some sort of filler that I can back fill the block, that's strong and paintable? Thanks

There are many 2-part, catalyzed polyester-filler ("bondo") products made for real cars that will work perfectly for your application.

This one is about the smallest amount that's commercially available, found in most auto-parts stores.

1/8 to 1/2 inch fills can be made without worrying about shrinkage, because the stuff cures through chemically, not by evaporation like the one-part fillers.
