Evercoat Feather Fill G2 Polyester Primer Surfacer, Gray 128 fl oz — High-Solids Shrink-Resistant Fast-Dry

Evercoat Feather Fill G2 is a high-solids, VOC-compliant polyester primer surfacer formulated to provide a shrink-resistant, fast-dry foundation for fiberglass, SMC, rigid plastics, and body repairs.

Feather Fill G2 combines high-build filling power with easy sanding and strong adhesion to multiple substrates used in automotive and marine repair. Developed from Evercoat’s decades-long experience in body fillers and primers, this gray 128-fl oz container delivers a user-friendly surfacer that sprays smoothly, sands quickly, and creates a reliable base for topcoats without excessive shrinkage.

How does Feather Fill G2 perform on repaired or uneven panels?

This primer surfacer is engineered to fill low spots and feather-edged repairs while maintaining dimensional stability during cure. Its high-solids polyester formula builds quickly and resists the common shrinking seen in lower-quality products, so repaired areas stay flush and require less rework.

• High-build formulation fills moderate low spots and pinholes
• Shrink-resistant chemistry minimizes re-sanding and re-filling
• Fast dry-to-sand time speeds repair cycles

What surfaces will this primer adhere to reliably?

Feather Fill G2 bonds well to fiberglass, SMC, cured body filler, epoxy primers and many rigid plastics commonly found in automotive and marine applications. Proper surface preparation (cleaning, sanding, and appropriate adhesion promoters where required) helps ensure consistent results across different substrates.

• Excellent adhesion on fiberglass and gelcoat
• Compatible with polyester body fillers and putties
• Works over epoxy primers and many rigid plastic parts with prep

What sanding and finishing steps work best with this polyester surfacer?

Feather Fill G2 sands easily once dry, letting technicians move from coarse to fine grits to achieve a smooth, paint-ready surface. Typical workflow advances from 180 to 220 and finishes with 320 grit, depending on the final paint system and desired surface quality.

• Sand sequence: start 180 grit, refine with 220 grit, finish 320 grit if needed
• Fast dry-to-sand reduces booth time and labor costs
• Produces a uniform base for basecoat/clearcoat or single-stage finishes

Is Feather Fill G2 compatible with modern low-VOC paint systems?

Yes — this product is formulated to be VOC-compliant while still delivering high solids and performance. It is intended as a primer surfacer that prepares repaired panels for a wide range of contemporary topcoats; always follow paint manufacturer guidelines for adhesion and clearcoat compatibility.

• VOC-compliant polyester primer surfacer suitable for many modern paints
• Acts as an even foundation for both single-stage and multi-stage systems
• Follow coating manufacturer instructions for best final finish adhesion

Who is this for: Evercoat Feather Fill G2 is aimed at collision repair shops, fiberglass and composite repair specialists, restoration technicians, and experienced DIYers who need a reliable, fast-drying primer surfacer that sands easily and adheres to a variety of substrates. It’s especially useful when working on fiberglass, SMC, and repaired panels that demand a high-build, shrink-resistant foundation before topcoat application.
