A bit of a thread revival.
Just some maybe useful info.
After using my studio a lot, and structures settling etc, I found some small cracks appearing in the joins of the infinity curve. They didn't show up too bad so was a simple one click fix in pp.
However, I didn't want them there so decided to buy some polyfilla flexible no more cracks type stuff. It was ok for a short while, then the cracks showed again.
I have now found that GRIPFILL is the best stuff. But, put on extremely thinly as it does not like being sanded at all.
That's it really, only useful if you're building a curve. GRIPFILL is £1.99 a tube compared to £7.99 for the other stuff.
