I am not sure I understand the tinting process

Basically, all the material is bedliner, but you start by applying a light grey bedliner which includes our powdered products to control texture and vertical build-up. You can get the base coat applied to your own standards and needs by controlling the powder type, powder quantity, and build first before applying your color choice.

After the base coat is applied,  you topcoat with our clear bedliner using just the liquids and auto grade tints or single part, single stage auto paint to tint the clear to your color choice.

The process is basically the same for our koi pond / water feature kits as well.
