I bought this to fix scuff marks on my Hyundai Sonata's bumper, thinking one can each of filler/primer, paint, and clear coat would be enough. Taping and priming went fine, but the paint process was frustrating. I mistakenly removed the diffuser cap (thinking it was a cap), causing globs and drips on initial application. After sanding (and removing some OEM paint), I bought more cans and used the diffuser properly—but the paint was thin, ran easily, and didn't cover well. Even after nine cans (YES NINE CANS), the color still doesn't match the OEM white, and I haven't applied the clear coat yet. It's puzzling why the primer does not come in white, it might just be a way to sell more paint. Bottom line: unless you're experienced, get professional help or solid advice before attempting this yourself.
