Do you think a high-quality coating

means no peeling, no rusting, and no fading?

You're right!

But to truly verify if it’s a genuinely good coating,

you usually have to wait two or even three years—

until problems slowly begin to show.

So for projects that require 15 to 25 years of anti-corrosion performance,

is there a way to validate it quickly?

Absolutely!

Let me show you a few simple tricks:

First, color difference comparison—to ensure consistent color and batch stability.

Second, adhesion testing—using cross-cut and pull-off methods.

Third, coating thickness testing.

If all results pass,

then the product is ready for export!
