Hi Hector. For a driveway, you need to apply a penetrating sealer. Coatings are not desirable since they can deteriorate from being exposed to the sun and can get slippery when wet. Penetrating sealers are stain resistant, but not stain proof. They only buy you time to clean a mess up. If you are primarily worried about oil, then what you should apply is an oil repelling penetrating sealer. We have two that we can recommend. The first is GhostShield 8510. The second is PS100 by Concrete Sealers USA. If you have any questions, just let us know.

Hi Jeff. Just follow the red link that we provided above. It explains the benefits of polyurea and lists three different vendors where you can acquire it.

Hello Jeff. Epoxy is a sealer. The clear coat that was applied is a sacrificial wear coat that should have higher abrasion and chemical resistance than the epoxy. You can’t just patch/fix the clear coat areas where the tire marks are. The reason is that coatings do not blend like paint on a wall does. Those areas would stand out like a sore thumb with roller overlap marks and a different sheen. What would be required is to sand out the tire marks and then degloss the entire floor with 120 grit sandpaper and then apply a new clear coat to the entire floor. We would recommend a single-part polyurea. They are much more resistant to tire marks (no coating is tire mark proof), they are extremely long-wearing, and one of the easiest coatings to apply.
