06Questions

Before you check out.

What exactly do I get?

Everything in the private Student Portal: the step-by-step lessons, 15+ printable finishing tools, tool profiles for tricky geometry and the shopping list. You pick your language inside the portal — English, Português, Deutsch, Türkçe, Italiano or Français.

One payment of $97. No subscription. It is a digital course, not a physical kit, and nothing is shipped.

Can I sell the prints I finish?

Yes. Sell them at a market, in a shop, or to a client.

What stays with you is the course itself: the lessons, the printable tool files and the shopping list are for your own use, not for resale or redistribution. See the Terms.

How do refunds work?

The Formula comes with a 30-day money-back guarantee. Email support@polishmaster.co within 30 days of purchase with the email address or receipt from your Gumroad order, and the refund is processed through Gumroad back to your original payment method. Read the full Refund Policy.

Does it work on every print?

The method is the same on every shape, but the finish you reach is not. Material, print settings, geometry, preparation, safety practices, tools, coatings, technique and lighting all change the result, so no specific surface outcome is promised.

What the method controls is the order and the stopping point, so you are never guessing whether a phase is finished.

Anything else? Email support@polishmaster.co.
