Isopon P40 - sets in less than 10 min (depending on temperature), it has
a glass fibre content. Sets a bit on the hard side, so smooth it well or
peelply it. Car fillers, (Isopon P38) are softer and ok when you find
your primer hasn't filled. (In spite of Graham 1's comment, they have
been used for decades without problems in the car and boat industries and
no-one I have spoken to finds them unsatisfactory, and after all the
standard SP paint is described as a car body paint.) P40 sets a bit fast
in current summer temps even in Scotland, so mix small dollops only (or
keep in fridge until wifey discovers it).
