Parts Desk Insights
Best Use Case: Best for low-density fairing/contouring work where you want an easily sanded shape after cure.
Common Issues: For best results, match the filler/fairing consistency to your job (too thick can be harder to shape; too thin can sag). After curing, plan for sanding/fairing to blend edges smoothly, and verify you’re using the correct WEST SYSTEM epoxy thickening approach for fairing (low-density) work.
