Applying Primer Too Thick
Problem: Paint takes forever to dry, creates runs or drips, uneven finish
Solution: Multiple thin coats are always better than one thick coat—wipe excess paint on bottle rim

How to Use a Touch Up Brush
Touch up brush application is straightforward and takes 30-60 minutes for most repairs.
-
Step 1: Clean The Damage Area
What You'll Need
- TouchUpDirect Brush Kit (includes colorcoat brush and clearcoat brush)
- Microfiber cloth or paper towel
- 400 and 800-grit sandpaper (optional, included in Platinum Kit)
- Painter's tape (optional, for masking)
Wash the scratch with soap and water, then dry completely. The surface must be completely clean and dry for paint to adhere. -
Step 2: Sand If Needed (Optional)
If the scratch is uneven or has raised edges, use 400-grit sandpaper to smooth the area. Sand gently in the direction of the scratch until the surface feels level. Wipe clean with a microfiber cloth and let dry completely. -
Step 3: Apply Primer
If the scratch exposes bare metal or plastic, apply 1-2 coats of primer first (included in Preferred and Platinum kits). Use the brush to apply thin, even strokes along the scratch. Stay within the damaged area—don't overlap onto surrounding good paint. Let primer dry 15-30 minutes before proceeding to colorcoat. -
Step 4: Wet Sand Primer (Optional, Recommended for Large Scratches)
Wet sand the dried primer with 800-grit sandpaper to create a smooth surface. Use light, circular motions and keep the surface wet. Wipe clean and let dry before applying colorcoat. -
Step 5: Shake the Colorcoat Brush
Shake the colorcoat bottle vigorously for 1-2 minutes. You should hear the mixing ball moving inside. This ensures even color distribution and proper metallic/pearl effect. -
Step 6: Apply Colorcoat
Tips:
- Use light brush strokes in one direction (follow the scratch line)
- Apply thin layers—build coverage gradually rather than one thick coat
- Wipe excess paint off the brush on the bottle rim before applying
Open the bottle and use the built-in brush to apply thin, even strokes along the scratch. Apply paint only within the damaged area—avoid overlapping onto surrounding good paint. Wait 15 minutes between colorcoat applications. Apply 2-3 thin coats until the scratch is filled level with surrounding paint. After the final colorcoat layer, wait 30-60 minutes before applying clearcoat. -
Step 7: Apply Clearcoat
Shake the clearcoat bottle for 1-2 minutes. Apply 2-3 thin coats of clearcoat over the dried colorcoat using the same brushing technique, waiting 15 minutes between each clearcoat layer. Clearcoat seals the color and restores gloss. -
Step 8: Let Cure & Polish (Optional)
Allow 48 hours for complete cure before washing or waxing. The repair continues to harden and blend during this time. After 48 hours of cure time, you can wet sand and polish the repair for an even smoother finish. Apply polishing compound with a microfiber towel in circular motions. This step helps blend the repair seamlessly with surrounding paint.
Common Touch Up Brush Mistakes To Avoid.
Proper Paint Agitation
Problem: Color appears lighter or different from your vehicle
Solution: Shake vigorously for 1-2 minutes before first use and 20-30 seconds between coats.
Overlapping Onto Good Paint
Problem: Repair is visible, paint buildup on surrounding areas
Solution: Stay within scratch boundaries—use painter's tape to mask if needed
Skipping Clearcoat
Problem: Repair appears flat, dull, and doesn't match surrounding gloss
Solution: Clearcoat is mandatory—colorcoat alone will not match factory finish
Using on Large Areas
Problem: Brush strokes visible, uneven coverage, difficulty blending
Solution: Use aerosol spray for areas larger than 2 inches for seamless finish
Not Sanding Rough Scratches
Problem: Paint won't adhere properly, peels, or rusts underneath
Solution: Sand scratches with raised edges smooth before applying primer/paint

How Long Do Touch Up Brush Repairs Last?
Applied correctly—with proper surface prep and clearcoat—touch up brush repairs last 3-5+ years. Longevity depends on a clean, dry surface for adhesion, thin coats with proper drying time, primer to prevent rust on bare metal, UV-resistant clearcoat, garage vs. outdoor parking, and regular washing and waxing.

Frequently Asked Questions
-
What size scratches can a touch up brush fix?
Touch up brushes work best for scratches smaller than a quarter (approximately 1 inch or 25mm). This includes door edge scratches, key marks, small scuffs, and linear damage. For larger areas, use aerosol spray instead.
-
How do I know if I need primer with my touch up brush?
You need primer if the scratch exposes bare metal or plastic. If you only see colorcoat damage (the scratch hasn't gone through to raw substrate), you don't need primer. When in doubt, choose the Preferred or Platinum kit—both include primer.
-
Can I use a touch up brush on chips?
Yes, but a touch up pen provides better precision for small chips. Brushes work best for linear scratches and slightly larger areas. For maximum versatility, choose the Combo (2-in-1 Brush + Pen) kit.
-
How many scratches will one touch up brush fix?
One complete kit (colorcoat brush + clearcoat brush) covers multiple scratches up to quarter-size each. Actual coverage depends on scratch depth and length, and how many coats you apply.
-
Do I need to shake the touch up brush bottle?
Yes, absolutely. Shake the bottle vigorously for 1-2 minutes before each use, 20-30 seconds between coats.
-
Can I use a touch up brush on plastic bumpers?
Yes. Touch up brushes work on both metal and plastic surfaces. For plastic bumpers, apply primer first (included in Preferred and Platinum kits) if the scratch exposes bare plastic substrate.
-
How long does touch up brush paint take to dry?
Touch up brush paint dries to the touch in 15-20 minutes between coats. Wait 30-60 minutes after your final colorcoat layer before applying clearcoat. Allow 48 hours for complete cure before washing or waxing.
-
Should I sand before using a touch up brush?
Sanding is optional but recommended for scratches with raised edges or rough surfaces. Use 400-grit sandpaper to smooth the area before applying primer/paint. For wet sanding primer on larger scratches, use 800-grit sandpaper.
-
What's the difference between Essential, Preferred, and Platinum brush kits?
Essential includes colorcoat brush, clearcoat brush, and prep solution—perfect for basic scratch repairs. Preferred adds primer brush for bare metal/plastic exposure. Platinum includes everything plus sandpaper and polishing compound for professional-grade finishing.
-
Will the touch up brush match my car's faded paint?
Touch up brushes match your vehicle's original factory color, not faded paint. If your car's paint has faded significantly from sun exposure, the fresh touch up may appear slightly brighter or more vibrant than surrounding aged paint.
-
Can I apply touch up brush paint in cold weather?
Apply touch up brush paint in temperatures between 60-80°F for best results. Below 50°F, paint won't flow properly or adhere correctly. Above 90°F, paint may dry too quickly. If you must apply in cold weather, work in a heated garage.
-
How do I store touch up brushes between uses?
Store bottles upright in a cool, dry place away from direct sunlight. Cap tightly immediately after use to prevent paint from drying. We guarantee that a product will last for 6 months, but if stored properly, most will last for multiple years.
-
Can I use the touch up brush for tricoat/three-stage paint?
Yes. If your vehicle has a tricoat paint system, you'll receive two colorcoat bottles—one basecoat and one midcoat. Apply basecoat first (2-3 coats), let dry, then apply midcoat (2-3 coats), and finish with clearcoat. Both bottles will have brushes.
