Do I need to prep the surface before installing this gasket?

Clean and dry the mounting surface thoroughly — remove dirt, old gasket residue, and grease. A quick wipe with rubbing alcohol works. The gasket adheres better to a clean surface and seals tighter.

What should I use to secure the gasket once it's positioned?

Test-fit the gasket first to make sure the length and routing work. Most installs use contact cement or flexible adhesive rated for gasket materials. Some applications use small fasteners — check your specific panel or engine bay layout to confirm which method fits best.

Can I return or exchange this if it doesn't work for my application?

Standard return and exchange policies apply — contact customer service with your order number and photos if needed. Keep the packaging and gasket intact if you think it won't work before cutting or adhering it.
