R&P Service Insight
Before installing body rail tape, confirm that the surface is clean, dry, and free of loose debris, old adhesive, wax, oil, or moisture. Proper prep helps the adhesive bond and allows the tape to compress evenly.
- Measure First: Confirm that 1.25" width and .188" / 3/16" thickness match the gap or rail surface you are sealing.
- Surface Prep: Clean and dry the application area before installing the tape.
- Compression Fit: This tape is designed to seal when compressed between compatible surfaces.
R&P Knowledge Hub
Compatibility: Compatible with applications requiring black 1.25" wide x .188" thick body rail, topper, trailer, or RV sealing tape. Verify measurements before ordering.
Vehicle / System Fit: Commonly used for truck toppers, body side rails, trailer body contact points, RV applications, and general cushioning or sealing use where the tape dimensions match.
Installation Notes: Apply to clean, dry surfaces. Confirm that the tape can compress properly without bunching, folding, or interfering with panel fit.
Performance Insight: The PVC body and polyester film backing provide dimensional stability, while the adhesive backing supports light-duty bonding to suitable prepared surfaces.

What This Means: This listing is for one 30' section of black #30 Mylar tape, part number TM125B. It is not listed as a vehicle-specific OEM-branded item.
Before Ordering: Verify tape width, thickness, length requirement, surface material, surface condition, and compression fit before installation.
R&P Repair Insight
When replacing old body rail or topper tape, remove worn material completely before installing the new section. Uneven old adhesive or dirt can reduce contact and prevent the new tape from sealing evenly.
- Check Old Tape Size: Match the existing tape width and compressed thickness before replacing.
- Check Rail Contact: Make sure the rail or mounting surface contacts the tape evenly across the full length.
- Check Environment: Avoid installing over moisture, dust, grease, oil, or loose paint.
