|I know fuzzy|
I tried my first sample to see how it works and it was horrible. I didn't prime my base and they immediately began falling apart. I tried again to have bases for my bikes. I primed the bases red and then applied the crackle. I waited a day and I came back to it. There was some over hang with the paste that I had to cut and file away. I was afraid that they would start breaking off. I was in luck. The priming allowed me to work with it and not have any chipping.
If you really like the GW brand, you should give this a try.
