Model Surface Prep with Mr.Hobby GSI-R191

Mr.Hobby GSI-R191 is a heavy cut polishing compound made for hobbyists needing a dependable coarse polish. It provides a strong initial abrasion to even out surfaces prior to finer finishing.

Initial Polishing Stage

The GSI-R191 compound targets minor surface defects and light scratches effectively. Its coarse grade is best used in the earliest polishing pass on RC bodies, plastic components and other model parts to establish a smooth base.

Tips for Controlled Application

Spoon a small amount onto a soft cloth or sponge and work it in using steady, light pressure to avoid overheating thin panels. Clean off any excess and proceed with finer polishes to raise the gloss level ahead of painting or decals.
