Fair price, easy to work with, very durable.
Perfect
Very easy to work with. Lightweight and dries hard. Its aircraft bondo
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.
A great product and very good service.
great, easy to use product
Product worked just as described.
Repeat customer on this product as it does a great job.
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.
Works well with styrofoam, sands to a nice feathered edge.
Q&A
We have added the MSDS sheet to the "Documents" tab of this web page. Please review it there.
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.
