Reviews

Used this to simulate the windshield gasket on a Stinson SR-9. Works very well and very easy to sand. Should be great on fillets. Much easier to sand and manipulate than epoxy and micro balloons. A bit hard to measure out, so using a scale would be the best way to do that. Would be nice for modelers if it were sold in smaller portions.

Poly-SuperFil sure is one good product . I use it for model airplane fillets and more. Also on woodwork, as I do general painting as my work. This stuff I tried on concrete some time ago still holding firm,sands ok also.Again, good stuff.

Lightweight product that is easy to work with, has a slow drying time and very smooth sanding qualities. Used it to make repairs to my Stinson to fair out where hard points and fabric meet and crack over time.

Easy to mix, apply, and sand. Extremely lightweight. Adheres well to any surface. Works great for filling dents. Im very pleased with the result. I believe it can be easily used for may applications, not just aviation use.

Q&A

Q: Can you either direct me to, or provide the MSDS for this product please? Cheers, Bruce

We have added the MSDS sheet to the "Documents" tab of this web page. Please review it there.

Q: Does Super-Fil (09-28250) work well on aluminum?

Yes. It is an epoxy base filler and adheres very well to aluminum, wood, and composites.

Q: Will Superfil crack or shrink over long time? Also, what is max depth of fill?

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.

Q: Does the filler require a chemical and / or mechanical bond?

This is an epoxy base filler and adheres to many surfaces, but a slightly abraded surface is recommended for the best bond.

Q: You mentioned an abraded surface. I have a well bonded paint, is it necessary to remove the paint and abrade the aluminum or will roughing up the paint surface be sufficient?

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.

Q: Does SuperFil work well on sheet metal?

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.

Q: Can Super Fil be used as a structural adhesive (like regular epoxy) to bond two pieces together?

It is not normally used as an adhesive, so we have no data as to how well it will work.

Q: What is the shelf life for 09-28250 SuperFil Part A & B?

This material has a 2 year shelf life in an un-opened container.

Q: When using in locations which will ultimately be epoxy varnished and fabric covered, should the filler go over or under the varnish?

It should go underneath the varnish. The varnish should seal the superfil.

Q: What can be used to dilute the Super Fil mix so it is not so thick?

Per Poly-Fiber: We do not recommend thinning or diluting this product.
