Will this creeper fit under my low-clearance vehicle?

The 20" wheel diameter keeps overall height minimal, but measure your specific undercarriage clearance before committing. Most standard passenger vehicles work fine; lowered or slammed builds may need verification.

Does polypropylene hold up to oil and coolant spills?

Yes. Polypropylene resists breakdown from petroleum products and coolants, so spills won't degrade the body. Wipe it clean after each use to maintain the wheels and bearings.

Can I use this creeper on concrete floors?

Designed for smooth shop floors. Concrete can be rough on wheels—test it on your shop surface first. If you're on heavy concrete regularly, check wheel wear after a few months of use.
