Mirka Polarshine 45 Heavy Cut Compound

By Mirka

Mirka Polarshine 45 (PC45-025L) is an extra coarse and fast cutting polishing compound that helps you save time and still achieve a perfect deep gloss finish.

Removes sanding scratches from P600 grit and finer quickly and permanently using a twisted wool pad. Designed for hard surfaces and coatings, especially within the marine sector.

Used in both production and restoration processes, Polarshine® 45 is ideal for one-step polishing of white and light-colored gel coat surfaces. For darker colors, Mirka recommends a second step with Polarshine® 10 to remove swirl marks.

Convenient 250ml, 1L & 2.8L size for small areas and touch ups, also available in larger sizes.

How can we help?


Will there be hands on demonstration?

Absolutely. We will have a boat in the shop to work on. We typically focus on the hull sides. All the Starke products, pads and machines will be on display and available for use.

Will there be classroom work?

Yes. We like to sit down and go over some over the basics. We will have a presentation and slideshow. We start by introducing everyone. We like to ask why each person came and what they wanted to gain from this experience. Once we figure that out we can then dial in the message to focus on where everyone needs the most information.

Is this an accreditation course?

Yes. Sign up for this course to become a Starke Certified Installer and be listed on our site and receive special discounts on Starke products.

If I am a DIYer, can I attend this course.
