Mirka Polarshine 25: Polish for gelcoat

Mirka Polarshine 25
Mirka Polarshine 25
  • Coarse polishing compound
  • Very suitable for gelcoats
  • Quick and efficient

Mirka Polarshine 25 is the perfect polish for polishing gelcoat. This coarse polishing agent from Mirka is designed to quickly and easily polish bumps and (sanding) scratches from P800 and finer from gelcoat surfaces.

Mirka Polarshine 25 was developed for application on gelcoats but you can also use the product well on all paint systems. However, we recommend polishing painted surfaces with Mirka Polarshine 35, as this polish is more aggressive and therefore more applicable to harder paint systems.

Benefits of Mirka Polarshine 25

  • Coarse polishing compound for gelcoats.
  • Emulsifying properties reduce the risk of surface drying or overheating.
  • Gives a beautiful shine.
  • Fast and efficient polishing agent.

Instructions for use 

Mirka Polarshine 25 is specially developed for machine processing but, if desired, can also be processed manually with a Farécla applicator waffle pad. For best results, we recommend processing this polish mechanically in combination with the Mirka lambskin polishing pad. The aggressiveness of lambswool in combination with this coarse polishing agent gives the most optimal result.

Working with lambswool may leave holograms on the surface. For this reason, we always recommend post-processing Mirka Polarshine 25 with Mirka Polarshine 10. This very fine polish removes residual holograms and gives a high-gloss finish.
