Imagine Bondo that: is easier to sand is adhesive finishes finer without pinholes remains workable for 10 plus minutes - can be spread and re-spread can be rough shaped / razor trimmed / sanded at different stages of cure takes overnight to fully cure before its ready for finish sanding is much stronger, for example, can hold up as an outside corner costs a lot more You are imagining Super Fil

An excellent, easily sanded lightweight filler. I began using 3M Glazing putty, but it doesnt sand as well as SuperFil. Also, a very little goes a long way!

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.
