using it to fill hairline cracks in fibreglass shower tray - can it be sanded, overpainted, and is it waterproof?

This is just a hardener. It is an additive for curing resin. It is not a resin itself. Thank you

does this work with big boy fibreglass

Hi Colin If you was originally supplied with red hardener with your product then this will do the job. Red hardener is used for a majority of fillers and fibreglass fillers. If need need any further information please do not hesitate to contact the Qpaints Team

Does this product garden resin jewellery and will it discolour the jewellery?

don't think so but depends on the resin you are using too. Alsodo a test run first.

Is this harder red or white in colour?

From memory its red but I used very little in the resin, so it did not really colour it. it did the job, but I did a test first to check that a small amount would harden the old resin I had.
