I know this sounds daft, used some car filler on a couple of places on my Landy yesterday afternoon. On the tin it stated it should dry hard with twenty mins of so, however what I didnt realise at the time that the tin had a plastic section which contained a small tube of hardner. Realising my mistake I spread the hardner over the top of the filler. Tested the filler this morning and it is still soft. Will it dry hard eventually or do I need to scrape the filler off and start again. Thanks

It will go off eventually but you might not live to see it. Scrape it off and do it again.

The hardner needs to be mixed with the filler until it's all the same colour with no streaks in it. usual mix is a pea of hardner to a golfball of filler.

What you are adding is a catalyst, in other words, the hardner will speed up the drying time, the more you use the faster it sets (although can cause fillers, resin etc... to loose strength and even catch fire - not good in a bin of soaked resin tissue!)

It would go off in about a year, so as said above, take it out and redo, if you can't get all the old stuff off, then with a small paint brush or something dab the area with hardner and mix it up a bit so that the new stuff isn't trying to stick to unhardened filler.
