When you need to fill seam lines, sink marks, or minor surface imperfections before priming, Mr. White Putty is the bench staple that gets it done. A solvent-based lacquer putty with a smooth, easy-to-spread consistency — it goes on clean, sands down easily, and leaves a surface ready for primer without ghost lines or shrinkage surprises.

Works straight from the tube or thinned with Mr. Color Thinner for finer application with a brush or old sprue tip. Once cured, it sands and scribes cleanly with no tearing or crumbling, which makes it a solid choice whether you're rescribing panel lines or just cleaning up a bad pour gate.

White base makes it easy to spot coverage, and it plays well under Mr. Surfacer or any lacquer primer in the Mr. Hobby lineup.

Not a structural filler. For deeper gaps look at Mr. Dissolved Putty or epoxy options. But for the everyday cleanup that separates a clean build from a rushed one, this earns its spot on the bench.

Compatible with: Mr. Color Thinner, Mr. Surfacer, Mr. Dissolved Putty, and most lacquer-based Mr. Hobby primers.
