Evercoat Feather Fill G2 Polyester Primer Surfacer - Gray 128 Fl Oz

In this review the Evercoat Feather Fill G2 Premium Polyester Primer Surfacer is examined from the perspective of someone doing automotive body repair on fiberglass and rigid plastics. The bottom line: this 128 fl oz gray primer is best for technicians and experienced DIYers who need a high-solids, fast dry-to-sand foundation that fills minor imperfections and adheres well to body filler, epoxy primer and SMC. It earns its place where good adhesion, easy sanding and reliable spray performance matter most.

Key Features

• Excellent Foundation Primer: Provides a high-solids base coat that holds down body repair areas and creates a consistent surface for any paint system.
• Easy Sanding: Sands smoothly with 180, 220, or 320 grit sandpaper allowing fast fairing and feathering of repaired sections.
• Highly Adhesive Formula: Bonds well to fiberglass, SMC, putty, epoxy primer and rigid plastics for secure layers before topcoat.
• Shrink-Resistant and Fast Dry: Dries to a sandable state quickly and resists shrinkage so repairs retain fill thickness through sanding.
• Smooth Spray Quality: Sprays evenly for an even build and good coverage, compatible with common spray setups including a 2.0mm tip.

Who It's For

The Feather Fill G2 is aimed at collision repair shops, restoration builders and experienced weekend mechanics who need a robust primer surfacer for fiberglass, SMC and rigid plastics. Its high-solids chemistry and fast dry-to-sand time make it useful where turnaround time and repeatable sanding are priorities.

Less experienced users who want a one-coat finish without sanding or those working on non-automotive porous substrates should consider a product specifically formulated for those uses; G2 is designed as a foundation primer to be sanded and finished before topcoat.

Pros & Cons

Pros

• Excellent adhesion to common repair substrates, reducing delamination risk.
• Notably easy to sand, with customers reporting good results using 240 grit within a day.
• Good coverage and sprayability, working well with standard gun setups for even build.
• Shrink-resistant formula maintains fill and thickness through sanding.

Cons
