Covercraft used to be good when Bob started it. They son Marty took over. Then they got the boys from Century Park Capital in there and started to buy up other cover companies. The fabric got thinner and cheaper and the thread wears out before anything else. Funny how marine covers can withstand the UV rays but Covercraft thread just rots away before the rest of it. I have 2 older covers that I've resewn with Sailrite lifetime thread. Used it on an older Weathershield cover when they used a thicker fabric. It still holds up. Now around 20 years later. I had ordered a replacement Weathershield after they had gone to 2 different thicknesses. I got the heavier one which was now thinner and it didn't last maybe 4 years and even the fabric was falling apart as well as the cheap thread. Yet another company that went to hell when the big boys took over. I don't or sell their crap anymore
