Installation of bath has gone to plan, all except a silly mistake of my own by putting a bit too much of my own weight on the edge of the bath when moving things around etc... Heard a loud crack sound, followed by a few swear words. The crack is on the outer rim of the bath, about an inch long, and stops just as it goes into the curved top outer edge of the bath. Now I know it's not going to affect how the bath works because fortunately it's only the outer edge, but I am worried about it growing, plus every time I see it I will be reminded of my stupid error. What is the best way to fix this? I've seen repair kits after a quick google but still unsure as the best way to approach it. Any help much appreciated!
