When seam lines and sink marks stand between you and a clean build, Mr. White Putty is the tool that closes the gap. A solvent-based lacquer putty with a smooth, workable consistency that spreads easily, cures solid, and sands down without tearing or crumbling, leaving your surface ready for primer with no ghost lines or unexpected shrinkage.

Works straight from the tube or thinned slightly with Mr. Color Thinner for finer brush application. The white base makes coverage easy to read at a glance, and once cured it scribes cleanly, so rescribing panel lines after filling stays predictable rather than frustrating.

Plays well under Mr. Surfacer and the full range of lacquer primers in the Mr. Hobby lineup. This is not a structural filler. For deeper gaps or large seams you will want Mr. Dissolved Putty or an epoxy alternative. But for the everyday surface prep that separates a clean Gunpla build from a rushed one, this earns a permanent spot on your bench.

Requires good ventilation. Lacquer-based product, use with an organic vapor respirator and active extraction.
