Custom Shop 6-Inch Plastic Spreader Tools 50-Pack — Flexible Disposable Spreaders for Body Fillers & Epoxy

These are 50 flexible 6-inch plastic spreader tools from Custom Shop made to apply and smooth body fillers, putties, glazes, epoxy resin, caulk, and adhesives.

Whether you're repairing a fender, doing a resin pour, or smoothing caulk around trim, having a reliable disposable spreader makes the job faster and cleaner. The Custom Shop 6-inch spreaders come in a bulk 50-pack so you can use a fresh tool for each material or stage without stopping to clean. The flexible plastic design acts like a small squeegee, giving even coverage and better control than improvised tools such as old credit cards or putty knives.

How do these spreaders improve auto body filler application?

The thin, flexible edge helps you feather filler edges and work material into curves and shallow contours. Compared with rigid metal tools, these plastic spreaders reduce gouging and leave a smoother surface ready for sanding.

• 6-inch length for reach and control on panel work
• Flexible blade spreads material evenly without digging in
• Disposable—use a fresh tool for different compounds to avoid contamination

Can I use them with epoxy, resin, and paint pours?

Yes—the non-porous plastic resists many resins and paints for short-term use during pours and leveling. They’re handy for moving resin around, removing high spots, and creating consistent layers in art projects.

• Works with epoxy resin, acrylics, and glazes in small pours
• Good for smoothing bonds and pushing material into corners
• Single-use reduces reaction or cure issues between different compounds

What advantages do these spreaders offer for caulk, glue, and general sealing?

The spreaders let you shape and compress sealant beads to a uniform profile, improving adhesion and finish. Their flexible edges are ideal for conforming to uneven joints and trimming excess without disturbing the seal.

• Evenly profiles caulk beads for tidy seams
• Flexible tip adapts to concave and convex joints
• Disposable option avoids cross-contamination of adhesives

How should I choose between a plastic spreader and a metal putty knife?

Plastic spreaders excel when you want gentler contact, single-use convenience, and reduced risk of scratching delicate surfaces. Metal knives are better for heavy bulk removal and when you need a perfectly rigid edge, but they require cleaning and can mar substrates.

• Choose plastic for finishing, light smoothing, and single-use tasks
• Choose metal for scraping, heavy filler removal, and rigid spreading
• Keep both types on hand for different stages of repair or craft work

Who this is for: craftsmen, body shop technicians, DIY auto repairers, resin artists, and general tradespeople who need a reliable, low-cost supply of disposable spreaders. The 50-pack is designed for workshops that use multiple compounds or perform many small jobs—providing fresh tools for each task to save cleanup time and prevent material cross-contamination. If you value control during finishing and want an economical option for smoothing fillers, caulk, or resin, these Custom Shop 6-inch plastic spreaders are a practical choice.
