Regarding what #2 said about 'I've spent a huge amount of time researching...', unfortunately, expensive coatings often fail with heavy denim use. I had issues with staining on my last car even after spending $200 on protection... total waste of money imo. Quick tips for safety:

• Get Coverking Rhinohide Custom Seat Covers Honda Civic for your commute.
• Use Husky Liners Weatherbeater Floor Mats Honda Civic to keep that red carpet dry.

I've spent a huge amount of time researching this for my own build and found some fantastic high-end alternatives. Since you want to bulletproof the interior, you should look at a tiered approach that includes both hardware and chemical protection.

• 3D MAXpider KAGU Floor Mats Honda Civic FL5 Black
• These provide incredible coverage with a premium look that fits the type r aesthetic perfectly. They dont slide around at all.
• Gtechniq Smart Fabric I1 AB V2 Fabric Protector
• This is a game changer for those red seats. It creates a hydrophobic barrier that prevents blue jean dye transfer and spills from soaking in. Its a professional grade solution.
• Xpel Ultimate Plus Paint Protection Film
• Instead of bulky guards, get some ppf applied to the door sills to prevent scuffs. For more technical details, i really recommend checking out the detailing sub-sections on the civicxi forums. Honestly, the gtechniq stuff is basically mandatory if you are wearing work jeans every day. It keeps the fabric breathable but incredibly resilient to stains!

I went through this exact stress last winter. The red carpet is a magnet for mud. I skipped the OEM stuff and got TuxMat Honda Civic FL5 All-Weather Floor Mats because the coverage is insane compared to Honda's mats. Also, get some DreamStick Seat Bolster Protectors right away. I saw wear on my bolsters within weeks from my work jeans, and those covers stopped it completely.

> I'm looking to spend around $500 to bulletproof this interior @Reply #3 - good point! Denim transfer is impossible to stop with just sprays. Looking at the thread, high-coverage mats and physical barriers are the only real solution. If the other brands are too expensive, SMARTLINER Custom Fit Floor Mats Honda Civic 11th Gen provide excellent carpet protection for the money. Also, get some Lamin-x Door Sill Guard Film to prevent boot scuffs... this combo keeps things clean without breaking the bank.
