It was too cold this weekend to try the Hairline Crack product, but I touched up a chip in my cabin with the 9 Second Gel Coat Repair. I need a second application, but it seemed pretty decent and certainly better than the chip repair product sold here in the US. I actually just got off the phone with them. They said the $30 shipping was a mistake and they refunded $15 of that. They also said they had to shut down their Amazon store as the international aspect of it kept causing too many issues. I hope to try the rest of the products within the next week and I will report back with pictures and perhaps some better news on purchasing the products in N. America.
