Wow. That is LONG (the tunnel garage). Nice boat too.
My recommendation is epoxy. Reflects light very nicely. And it's easy enough and cheap enough.
Do you have another utility room or building to use as a garage to work on things? And Park cars? Or is it just that one? At 18 x 52 I would think that is enough room beside the toys to have a narrow bench and some storage and room to walk, but I thought I would ask.
Congrats! Looks super nice.
That's a nice set up, congrats. Not to ask too stupid a question but this doesn't happen to be in the Chino Valley area does it. The wife and I just looked at new homes in that area with virtually the same configuration. Could just be the same builder too. Just wondering.
