I wanted to see how Krylon Fusion would behave on the Tech Shed’s vinyl windows before treating it as a real solution. The early result was better than expected.

Watch the test

First impressions

• Good adhesion to the vinyl surface
• No meaningful dripping during the test
• Strong self-leveling behavior
• A much cleaner finish than I expected from a quick experiment

This is still an early result rather than a years-long durability verdict. The useful part is documenting how it performs now, then revisiting it later after weather and time have had a chance to weigh in.
