Wash or rinse first
Remove salt, sand, loose grime and other abrasive contamination before polishing fiberglass or gelcoat.
Fiberglass & gelcoat application
Dull or chalky gelcoat? Match the polishing method to the oxidation level.
Koenig can be used by hand for routine marine maintenance and light oxidation. Heavier oxidation or weathered fiberglass may respond better to an appropriate buffer or polisher.
Choose the correction level
Start with the least aggressive method that works.
Test by hand
Apply Koenig to a manageable section with a clean towel and evaluate improvement in gloss and surface condition.
Use a buffer when needed
For heavier oxidation, dull fiberglass or chalky gelcoat, use Koenig with an appropriate polishing pad/buffer after a small test area confirms the process.
Buff and maintain
Finish with a clean microfiber towel. Once the surface is corrected, periodic maintenance should require less aggressive work.
What to expect
Light oxidation and severe oxidation are not the same job.
Good condition
Routine hand application can clean, improve gloss and leave a protective finish on compatible fiberglass and gelcoat.
Moderate oxidation
Machine polishing can increase correction and consistency on larger weathered areas.
Severe oxidation
Deeply weathered or damaged gelcoat may require a more involved restoration process before final polishing and protection.
