USC ICING 26006 Polyester Finishing Putty - 24 fl oz

Ultra-Smooth Finishing Putty for Pinholes and Minor Imperfections

USC ICING 26006 is a pourable, brushable polyester finishing putty made for the final stages of surface preparation. Its creamy, self-leveling formula spreads smoothly over properly prepared surfaces and body filler, filling pinholes, sand scratches, chips and shallow imperfections before primer and paint.

ICING cures to a tack-free and stain-free surface that is exceptionally easy to sand. Use it as a thin finishing coat where a smoother surface is needed before applying polyester, 2K urethane or 1K primer.

This package includes one 24 fl oz tube of USC ICING and the required blue benzoyl-peroxide cream hardener.

Recommended Uses

Use USC ICING for minor body work and surface imperfections no deeper than 1/8 inch after sanding. Typical repairs include:

• Pinholes in body filler or fiberglass repairs
• Sand scratches and shallow sanding marks
• Small chips and surface scratches
• Minor low spots and cosmetic imperfections
• A final finishing coat over fully cured body filler

ICING is not a structural filler. Deep damage, flexible-plastic repairs and structural SMC repairs require a product designed for those applications.

Compatible Substrates

• Steel and other properly prepared metal
• Aluminum
• Fiberglass
• Fully cured body filler
• Wood
• 2K primers
• Aged and sanded OEM topcoats
• Galvanized and other zinc-coated steel
• SMC for cosmetic repairs only

For structural SMC repairs exposed to high stress or flexibility, use an approved SMC repair system. For flexible plastic, use a flexible-plastic repair product such as USC PRO-FLEX 26037.

Mixing Instructions

1. Bring the ICING putty and included blue BPO hardener to room temperature. The minimum recommended material temperature is 68°F.
2. Knead the hardener tube before dispensing.
3. Place the required amount of putty on a clean, non-absorbent mixing board.
4. Add blue BPO hardener at 2% by weight, which is a 50:1 putty-to-hardener ratio.
5. For a visual estimate, place an edge-to-edge ribbon of hardener across the center of a putty puddle approximately 4 inches in diameter. Larger batches require proportionally more hardener.
6. Mix thoroughly with a plastic spreader using a folding motion until the mixture has a uniform color with no streaks.
7. Apply immediately. Approximate setting time is 3-5 minutes at 68°F.

Surface Preparation and Application

1. Clean the surface. Remove dirt, oil, grease, silicone and wax using a suitable surface cleaner.
2. Dry completely. Do not apply putty over a damp or contaminated surface.
3. Create mechanical adhesion. Featheredge the repair with 80-180 grit abrasive.
4. Apply a thin layer. Use a plastic spreader and firm pressure to maximize contact with the prepared substrate.
5. Build only as needed. Sand a cured layer before applying an additional layer. Do not exceed a final sanded thickness of 1/8 inch.
6. Do not apply over fresh or uncured coatings.

Sanding and Topcoating

At 77°F, USC lists a typical sanding time of approximately 15 minutes. When the material is fully hardened, begin sanding with 100-180 grit abrasive. Follow with 220-400 grit as needed to refine the surface for the selected primer system.

USC ICING may be topcoated with polyester primer, 2K urethane primer or 1K primer. Always follow the primer or paint manufacturer's preparation, film-build and recoat instructions.
