Filler not cured...doh!
Any ideas, other than dig it all out and re-do? It's a fairly large section. Put in the recommended hardener but it was possibly too cool for
that, it started to tack but never went hard. I spread a thin film of hardener on the surface and heated it up to 30C or so and it went fairly firm to
hard, but has kept a soft surface. Trying to decide whether I have to dig the lot out or if it can be rescued!

Usually if a thin coat of 'strong' filler is applied over the top, the catalytic reaction turns the dodgy filler too - it can sometimes
take a few hours though.

had this many times in the winter
get a hair dryer and heat it up till its too hot to touch, the surface will then become hard once cooled down. Usually it turns quite a bit darker as
the curing process starts up. Same thing can be done to GRP is it has not gone off properly.
It is also best to buy anti clogging sand paper when dry sanding in the cold weather as this lasts a lot longer
oh and don't put hardener on the surface that will just make a mess and won't mix in anyway

You can do it quickly. You can do it cheap. You can do it right. – Pick any two.
