Q-cell vs glass bubbles - what do you prefer

[slawosz]

Hi,
I am doing some filling job, using West System and Q-cell and glass bubbles. I found Q-cell much harder to mix into resin, and difference between q-cell filler and glass bubbles is hardly noticeable (I am doing small bits only). What do you prefer for your jobs?

Depends what the job is.
Sometimes use glass bubbles, sometimes chopped glass strands, talc, silica.

So when you would use Q-cells and when glass bubbles?

Have a look at the technical data sheets. They are, as near as makes no difference, the same thing ie 50 micron sodium silicate borate glass spheres.

Every day a school day.. Not seen Q-cells. Always used glass bubbles and found them easy. Lot of fairing coming up soon, so interesting.

Whatever is to hand. At my mates place, he has Qcells. I have SP and BlueG glass bubbles.
West often wants a bit of breathing on with the hot air gun.

Thanks. So I dont see big difference now. Q-cell is cheaper, but its much harder to mix as its much lighter then glass bubbles. For me price doesn't matter because I have so much money I use so little, that 1 lt will last forever.
