Hi all, I have been using some P 38 from a tin for a few months now and it is starting to go a little less soft and does not mix so well either.  I think it goes off a bit sooner than before as well.

I have always put the lid back on as soon as I take some out.

Is there a liquid that will restore it / soften it to what it was a few months ago?
regards to all, Roy

Use a small amount of cellulose thinners before adding the catalyst.

Does adding the thinners change the curing time at all?

As a Proffesional Panel beater I will give you a couple of piecs of advise...firstly throw it away as it baisically dried out,you should never add thinners to it...reason being it will casue shrinkage etc etc.
Second piece of advise stop using it and use Easy light or top stop far superior less prone to drying out and a lot easier to rub down see painting guid above on it

Hi All, belated but my 2p's worth...
Mixing thinners isn't going to add any 'goodness' to the mix .. bad pun i know.
If adding chemicals we need to start understanding chemistry ... i dont & really don't want to damage myself .... so Stavros i'm in agreement ... mag to grid .. get rid!
Having said that i have, when really pushed, added the appropriate resin to fillers to get on with a job.
Adding resin you re intreoduce the styrene which is probably what was lost in the first place
 (assuming it's a styrene based filler)
What i have said regards thining is not to be taken as advice!
The best asdvice was given by Stavros get fresh stuff!
Regards,
Kim

Is P40 still the way to go or is there something better for fixing prop tubes etc?

As has been said the best thing would be to bin it. However if you're determined you can thin it with Polyester resin.

I use this stuff..

[Stavros]

P40 gets my vote for propshaft fixing and any other joint that needs strength body filler of any form does not as filler does not give you any as it is talc based

What about mixing a little fibre glass resin with it... it works the other way round.

[Stavros]

No as i said earlier THROW ITAWAY..........is your pride and joy and all your hard work not worth a NEW tin of filler.

I can not tell it any plainer ,if you must insist on adding resin etc to OLD dry filler then dont blame anyone only yourself if it doesent dry'or is impossible to sand down and ruins your model as everyone on here will simply say




Stav told you NOT to do it



Fact..........manufacterers spend thousands developing their products....think about it.....rant over

I went to buy some wood filler for a little job, and a mate of mine who works at b&q advised me to go get some car filler as it was the same stuff as decorators filler but half the price. (and easier to work).

If it's the 'same stuff' how come it's 'easier to work'?

I assume you are talking about the Ronseal High Performance two part wood filler which smells the same as P38 but is not the same filler. This is for wood and curing wet rot, where as the P38 one is for repairing metal including galvanized.

[grendel]

I was just told that a lot of professional decorators used the car filler as it was cheaper (I dont think it was p38, I think it was a more modern version).
