A white tub-and-tile finish was among the coatings I bought for the project.
The featured Amazon option is DWIL Tub-and-Tile Paint Kit.
Where it fits my build
I marked the opening beneath the passenger seat and used a drill, reciprocating saw and grinder to make it. I then drilled the mounting holes and sanded the cut area.
The finishing sequence included two coats of primer and two coats of white paint. That put the cutting, abrasive preparation and coating into distinct steps before the heater mounting continued.

My build notes
The opening changed from marked sheet metal to a cut edge and then to a painted mounting area. The sequence in the photos explains the role of the finishing supplies alongside the cutting tools.
Cutting the opening was followed by abrasive preparation and coating before assembly continued.
Alternative products
Two alternatives to compare
DWIL and the thirty-five-ounce kit provide water-based semigloss coatings with application tools. Bathworks combines a gloss white coating with a separate surface-preparation liquid; these are roll-on approaches rather than the aerosol format in my purchase record.

This roll-on kit combines a white refinishing coating with a separate surface-preparation liquid. Its coating uses an acrylic-resin formulation for tub-and-tile refinishing.
