Can I apply multiple coats of products in the XRC line?

Yes, you can apply multiple coats to build up extra protection. We recommend 2 coats when possible.

What will happen if I apply too much material?

Nothing bad will happen to the end product, but visually the product will run or drip if applied too heavily.

How long does XRC-106 take to dry?

In normal conditions, it will take 2–4 hours to dry and approximately 16 hours to fully cure.

Is XRC-106 UV stable?

No, XRC-106 is not UV stable. If you're looking for a product that will be out in direct sunlight all the time, you'll want to use XRC-2001, which is UV stable, or apply a clear coat on top of the XRC-106 product.

What is the difference between XRC-106 and XRC-110?

XRC-110 is a thicker, heavier version of XRC-106, so it has a higher viscosity and takes longer to dry and cure.

What does finished XRC-106 look like?

A matte finish that is smooth, firm, and flexible.

Road Guard Liquid Rubber Undercoating is designed to protect and extend the life of your vehicle undercarriage. It forms a continuous barrier that seals metal surfaces from moisture, oxygen, and road salts — the primary causes of rust and corrosion. It penetrates into seams and crevices where moisture typically collects and causes hidden rust. This product is particularly valuable in northern climates where road salt is heavily used in winter protecting steel frame members, cross-members, and floor supports from long-term corrosion.

Features & Benefits:

Completely seals the undercarriage against water intrusion from rain, puddles, and road spray
Prevents moisture from wicking into seams, joints, and overlapping metal panels
Keeps underbelly insulation dry, maintaining its thermal efficiency
Does not need semi-annual reapplication like some protective sprays
Multiple coats can be built up for extra protection
