Hi. First time posting, and hope to get some advice on my 2003 Hot Springs Sovereign model. It takes a lot of direct sun and the wood skirt/siding has deteriorated badly and needs to be replaced all the way around. I've had contractors (not spa specialists) tell me that the cost would be prohibitive (2K) and I should just consider a replacement. Is there an easy, reasonable fix to replace the siding with something durable? I hate to toss an otherwise good spa, but have to do something because the inner insulation is now exposed and things will only get worse. Thanks.
