Zinsser MH Ready Patch Professional Spackling & Patching Compound combines the workability of spackling paste with the strength of plaster. Rust-Oleum describes it as smooth, easy to apply and sand, and very hard when cured, for holes, cracks and gouges in wood, drywall, plaster, metal and masonry.

At 1/8 inch thick, one gallon covers about 13 sq ft; most nail-hole and crack repairs use far less. Coverage depends on the depth and size of what you fill.
Ready Patch cures very hard and may be harder to sand after drying overnight. Fill very deep holes with an epoxy wood filler or cement patch, and use caulk where caulk belongs. Removing old paint can release toxic lead dust; see the data sheet for lead-safe practices. Read the Ready Patch technical data sheet.
