POLY-FIBER SUPERFIL EPOXY A&B
I am a lifelong model Airplane enthusiast. I’ve been building with Balsa and Foam and Fiberglass etc… for over 30 years. I had no idea this product existed until a Facebook group member posted about using it on a 1/7 scale P-40 Warhawk. Intrigue set in and I ordered some to try out because I’m always looking for new and different products and tools that can improve my builds. Let me just say WHERE HAS THIS STUFF BEEN ALL MY LIFE! I feel like I discovered a 2-part cheat code and everyday I find a new way that SuperFil surprises me. This is now a must have on my shelf and a lifelong relationship has been formed. A beyond excellent product that has forever changed the way I build and repair my airplanes. I give it a 20/10 and HIGHLY recommend anyone on the fence give SuperFil a chance, it will NOT disappoint!

Yes. It is an epoxy base filler and adheres very well to aluminum, wood, and composites.
Superfil is an epoxy base material and will not shrink or crack over time like polyester base fillers. The manufacturer does not list a max depth.
This is an epoxy base filler and adheres to many surfaces, but a slightly abraded surface is recommended for the best bond.
No, it is not necessary to remove the paint. Just be aware the Super-Fil will stick to the paint, so if the paint chips off the structure, so will the Super-Fil on it.
Yes, It will work on clean metal.
Per Vendor: It can be used as filler on metal, sure, but it should be primed over to seal it.
It is not normally used as an adhesive, so we have no data as to how well it will work.
This material has a 2 year shelf life in an un-opened container.
It should go underneath the varnish. The varnish should seal the superfil.
Per Poly-Fiber: We do not recommend thinning or diluting this product.
