Frequently Asked Questions
Are breathable tarps better than waterproof ones for long-term storage?
For long-term indoor or carport storage, breathable canvas is generally better because it lets trapped moisture escape and reduces risk of mildew and corrosion. Waterproof poly is better when the vehicle is exposed directly to rain and UV, but it should be used with padding or a soft liner where it contacts paint to avoid abrasion.
How do I prevent a tarp from scratching my car or motorbike?
Use a soft tarp material (canvas or a tarp with a smooth interior finish), avoid direct rubbing by tensioning the tarp so it doesn't flap, and add a layer of felt, microfiber, or foam at contact points. Secure grommets and tie-downs so the cover holds its shape and doesn’t rub against paint in wind.
What size tarp should I buy for my vehicle?
Measure length, width and height of your vehicle and add 1–2 feet around each dimension for secure tie-downs and coverage. For a single motorcycle a small canvas (8x10) is often enough; for sedans choose 12x16 or 18x24 depending on extra clearance; choose 20x20+ for SUVs or to cover a car plus storage items.
