Why Paint Sealant Matters

Paint sealant is the invisible armor that keeps your paint smooth, slick, and protected. Unlike traditional wax, which lasts a few weeks, a high-quality sealant like Tough As Shell provides months of protection against UV, water, and contaminants — while enhancing gloss and depth.

When applied properly, it creates a slick barrier that repels water and makes future washes faster, easier, and safer for your paint.

Sealant vs. Wax vs. Ceramic Coating

It’s easy to get confused between the different types of paint protection. Here’s a quick breakdown:

Protection Type Durability Gloss Level Ease of Application
Wax 2–4 weeks Warm & deep Easy
Paint Sealant 4–6 months Glossy & reflective Easy to moderate
Ceramic Coating 1–5 years Extreme gloss Advanced

Paint sealants like Tough As Shell sit perfectly between wax and ceramic — offering long-lasting results without complicated prep or application.

Before You Begin: Proper Prep

Surface prep is everything. Sealant bonds best to a clean, smooth surface. Here’s how to get there:

  • 1️⃣ Wash the car thoroughly with The Super Soaper to remove dirt and residue.
  • 2️⃣ Clay the paint using a clay mitt or bar to remove embedded contaminants.
  • 3️⃣ Polish lightly with Picture Perfect Polish if your paint feels rough or dull.
  • 4️⃣ Dry completely using a Massive Drying Towel.

Step-by-Step: How to Apply Paint Sealant

Step 1: Choose Your Application Method

You can apply sealant by hand using an applicator pad or with a dual-action polisher and soft finishing pad. For most enthusiasts, hand application is simple and effective.

Step 2: Apply Evenly

Spray or apply a few drops of Tough As Shell onto your applicator. Work in small sections (2’x2’), spreading the product evenly in cross-hatch patterns.

Step 3: Allow to Haze

Let the product sit for 1–3 minutes (depending on temperature and humidity). You’ll notice a light haze forming on the surface.

Step 4: Buff Off with a Microfiber Towel

Using a clean Everyday Microfiber Towel, gently buff the area until clear and streak-free. Flip the towel often for best results.

Step 5: Let It Cure

Allow at least 4 hours before exposing the surface to water. For maximum protection, avoid washing for 24 hours.
