Body filler

[JimM169]

Hoping to tidy up my ageing Focus next week, it's got a couple of small rust patches and dents that will need stripping, filling and painting. Been years since I've done anything like this so just checking if there's a 'go to' brand of filler that people use these days or are they all a much of a muchness? Probably just grab a twinpack of Isopon P38 & P40 if there's nothing better out there?

I'd be sticking with the P38/P40 if it was me.

There's plenty better than isopon but they're meant for trade use so I don't know if they come in small sizes.
For example Upol Fantastic is a good filler.
If you're using chopped strand they're all much of a muchness

Not used it myself, but a quick google brings up 880ml bags of Fantastic.
