how do I repair a fiberglass bath

[slate1234]

Hi all could do with some advice, I have been retileing the bathroom and dropped a tile on to the edge of the bath, there is a crack about 3/4" long just woundering if the bath repair kits work or is there another way someone could suggest, I have never worked with fiberglass but am a joiner so have quite a lot of tools,
Thanks

Replace it there only fibreglass on the outside , the inside is some kind of plastic I doubt you will get a decent match to the repair
