why does yours have a pot life, is it a 2 pack?

...when spraying on [sprayable] polyester filler? Will cellulose thinners be OK?
If the stuff has a pot life of 25 minutes, how much should I mix per batch and expect to use it all in 20 minutes? Not a lot I shouldn't think.
100ml?
Depends how much youre applying!
Do it small bits at a time until you get a feel for how much goes on.

It is polyester (like normal body filler) so has a hardener that you mix with it. I like the idea of cellulose spray putty. 1 part means it
doesn't set in your gun if you don't keep your eye on the clock.
So what do I use to clean the gun then?
If you use the cellulose you clean with cheap cellulose thinners.
na I'd rather stick to my spray putty tbh you just clean it with normal thinner. Drys in about a day (depending on how thick you sprayed it) and
is easy to sand. I've use it on heaps of cars rather than spend ages filling and sanding bodywork.
What's this for? getting the cabin scooter ready for its final colour coats?
Yes, its for the cabin scooter. I sprayed 2 of the panels at the weekend with cellulose primer. They need something a bit stronger to fill the
surface. I thought they looked quite good until I painted them. There's still a lot of filling and sanding to do on large parts of the car but
if I can get a few panels primed and ready to paint, it might improve my motivation a bit.
I have the polyester filler in the post. I have cellulose thinners to clean the paint. Will it do the polyester as well or do I need something else?
Well it’s up to you but considering all the time and effort you've put into the car so far I suggest you try some on a test panel and maybe some
of the spray putty too. Halfords or Autosave tend to stock it and then decide which to use. I know what I'd use but that’s just me.
On repairs to GRP in the past I've actually just brushed a coat of the spray putty straight out the tin, left it to dry over a couple of days and
then wet sanded it down ready to paint with 600 grade paper. I've also used if on rusty surfaces like old headlamps and a year later with just
the putty on them there’s no sign of rust so it must be totally water proof.

Colin - if you are spraying any polyester, I would suggest you get acetone to flush the gun through. You can also get acetone substitutes, but they
tend to leave a sticky residue.
Remember that polyester will go off faster when in a large container - I miced up in your gun, it will go off a lot quicker than the thin film you
have just sprayed.
And just to be a PITA - epoxies use hardener, polyesters use catalyst! They are very different beasts!
Acetone. That's the answer I was looking for. I have some too. Hardener. Catalyst. The stuff in the smaller bottle that makes it set. I
understand the difference but tend to use "hardener" as it is the stuff that makes the product go hard.
You seem to be falling behind on your duty to keep regular photos in your archive Certainly doesn't look ready for spraying yet
Yeah. Photos of random body panels coated in filler don't look all that good. When I get something that looks good in the primer then I'll post some more pics.

I went and asked for the stuff in the little bottle that makes it go hard and got something entirely different 
sorry couldn't resist!!
