Evercoat Polyester Primer Surfacer Feather Fill G2 — 128 fl oz Gray, High-Solids Shrink-Resistant Easy-to-Sand

Evercoat Feather Fill G2 is a high-solids, shrink-resistant polyester primer surfacer made to create a durable, easy-to-sand foundation on fiberglass, SMC, rigid plastics and common body repair substrates.

Feather Fill G2 blends Evercoat’s decades of bodywork experience into a VOC-compliant primer surfacer that balances adhesion, fast dry-to-sand time and smooth sprayability. It’s formulated to lock down repair areas, fill slight imperfections, and accept standard automotive topcoats without lifting or excessive shrinkage. The gray, high-build formula lets technicians work quickly through feathered edges and blended panels while maintaining strong bonding to fillers, putties and a variety of plastic materials.

How does Feather Fill G2 perform on different substrates?

G2 was developed to adhere to many automotive substrates, including fiberglass, SMC, body filler, epoxy primers and rigid plastics. Its polyester chemistry provides mechanical and chemical compatibility with common repair materials so you get a consistent foundation across mixed repairs.

• Fiberglass & SMC: strong adhesion without lifting or cracking
• Body filler & putty: bonds over cured fillers for seamless transitions
• Epoxy primer and paint systems: accepts topcoats after standard prep
• Rigid plastics: adheres when proper plastic prep is used

What is the sanding and application workflow with this surfacer?

The product sands easily once dry, helping you move from spray to finish quickly. Recommended grits vary by stage: start heavier to level high spots, then refine to fine grits to prepare for primer-sealer or color. Proper mixing and spray technique are key to achieving the advertised fast dry-to-sand times.

• Spray: apply in controlled, even coats using standard spray equipment
• Drying: quick tack and fast dry-to-sand times under normal shop conditions
• Sanding: use 180, 220, then 320 grit as you progress to final finish
• Finish: ready to accept primer-sealer or color when sanded smooth

Will Feather Fill G2 resist shrinking or cracking during cure?

The G2 formulation is engineered to minimize shrinkage, preserving the profile of bodywork and preventing sinkage in filled areas. This stability reduces rework and makes it easier to achieve consistent, predictable results across multiple repair zones.

• Shrink-resistant polyester minimizes sink-back at feathered edges
• High-solids build covers light imperfections in fewer passes
• Uniform cure reduces the need for repeated filling and sanding

Who this is for: Feather Fill G2 is aimed at professional collision repair technicians, auto restoration shops and experienced DIYers who require a reliable, high-build primer surfacer that bonds to a variety of substrates. If you need a VOC-compliant product that sands smoothly, accepts topcoats well, and reduces rework on mixed-material repairs, this primer surfacer is a practical choice.
