Plastic access panels are definitely better for garages with big temperature changes. They don’t expand/contract as much as metal, so the fit stays tight, and no risk of rust from humidity or condensation. Look for UV-stabilized, heavy-duty ones that won’t become brittle. A reliable choice is this reinforced plastic panel https://www.amazon.com/Access-Panel-Drywall-Plumbing-Durable/dp/B085617TBL?tag=contractorhub-20 available in several sizes, impact-resistant, and designed to handle outdoor-like conditions indoors. The textured surface takes paint well for matching garage walls, installation is just cut and adhesive, and the removable door makes valve maintenance quick and easy without any visible screws or latches.
