My hot tub just arrived after a super long wait with damage to the acrylic shell. Seems a fork lift hit it at some point. I was given the option of a return with new one to ship when available which I assume will take forever or a spot repair with some money back. What would you do? I’m particularly concerned that the crack spreads over time and my whole tub is ruined! Is that a rational fear / can the crack spread? Local Spa dealer claims it will not spread.
