Hey guys! Some cracks have developed in my hot tub cover. Its been 3 years since we've been using it. I think its time to replace it. But my husband says cracks are usual and there is no need for a replacement. I strongly feel there is a need of replacement and I need to convince my husband for that. I tried asking some of my friends and I got mixed reviews. What should I do? Are cracks a sign of hot tub cover replacement. And also for replacement where do I find a good hot tub cover?
