I used their primer filler on top of the conventional Europa filler. It
performed
well but did shrink very significantly over a period of 6 to 8 months; more
so than standard automotive polyester 2-pack primer filler ( by way of
comparison
( no- I didn`t use this on a Europa)). So quite a few blemishes and pinholes
did eventually reappear.
The cost was utterly ridiculous ( =A3125 per (US) gal. delivered in the UK). In
future I`d think further ahead and order direct from Aircraft Spruce at $85/gal.

Subject: Re: Substitute filler
My colleagues and I are at the end of constructing the first stage of an
xs model, and were thinking of using the superfill filler produced by Polyfibre,
as opposed to the standard filler supplied by the factory. We saw it at
the Cranfield PFA rally and it seemed pretty impressive. Does anyone have
experience
of the system, or hold views on substituting the material?
It is marvellous stuff to use. Not cheap but does the job beautifully. Jon
Goldenbaum of Polyfiber gave a very impressive demonstration of filling a Europa
wing a Cranfield and had most of the work done on one side in two days. I
managed to fill, profile and sand a stabilator side in three hours work with
Superfil.
Their primer and top coat are great to work with as well.
