Does anyone know of a slow curing body filler. Or what is the minimum amount of hardener that can be added to the filler.
-
You can use Easy fair, which is an easy spreading epoxy filler.
It takes hours to cure through (I leave it overnight), and unlike polyester putty it's waterproof too. However it is much more expensive than polyester filler, and I usually use a quick wipe of polyester filler over the top to fill any imperfections, as polyester filler does spread a bit easier and feathers well.
You can also retard the cure of polyester filler by chilling it before use.

Usual ratio is a pea to a golf ball....fillers I can asure you don't like to have to little filler as they will not harden properly and this will leave a horrible mess rest assured on this.
WHY do you want a slow curing filler ?

It's to fill in small gaps between two bulkheads and a companioway, which will be very awkward to get at to sand. So I want to get it as smooth as possible.

Easy light or top stop filler that's your best bet they are silky smooth and don't give air bubbles....mix a bit at a time it will go off in ten mins max and is sandable really is user friendly not like some other fillers I can name.
Make your own sanding pads out of scrap plywood and carpet glue or evo stick paper on it....or use some emery nail files...DONT TELL THE WIFE you have knicked them HA HA ...simply RUN for cover

If your gapes are small and it is only cosmetic and not structural use decorators caulk , it's not a silicon and paints well, fill gap and smooth with a damp finger or tool it goes smooth , paint when dry .

What about knifing putty available from good car accessorie shops, would that do?

Not very strong, plus high shrinkage. Knifing putty, spot putty, whatever you like to call it, is really for filling sanding scratches and pin holes, not suitable for filling gaps.

I have used isopon p38 on three of my boat builds not had any problems and its easy to file and sand to a smooth finnish.

I've just used Micro Balloons mixed with Z-Poxy finishing resin. You can make the mix as stiff or as runny as you like and it takes at least three hours to go off. Working time is about half an hour. https://www.deluxematerials.co.uk/en/rc-modelling/72-microballoons-5060243900593.html (https://www.deluxematerials.co.uk/en/rc-modelling/72-microballoons-5060243900593.html)
