I can smell the resin- has it leaked

Unlikely - This is Polyester resin and has a very powerful and strong smell- The smell will often permeate the plastic bottle and cardboard packaging giving the impression of a leak.

Does the Resin stay BLUE

No- The Blue colour is just a dye that dissipates once the resin is activated. it then takes a more natural colour maybe slightly green. See the cured fibreglass sample above.

Is the resin Lloyds approved, What does Lloyds approved mean?

No the resin is not Lloyds approved but its is a similar resin. Lloyds approval is from Lloyds insurers specifically for Marine Craft repairs. Such marine repairs often need approved repair products to maintain insurance cover.

What is the working time ?

Ranges from 10-20 minutes : Directly depends on ambient temperature & volume poured. Hot temps and large volumes rapidly reduce working time to barely minutes on a very hot day. Avoid very hot conditions , mix small manageable quantities & repeat.

Can I used the resin to Cast or fil voids.

No - The resin on its own will significantly overheat. However if mixed with "Marble filler Powder" at 1 to 1 by weight then castings and large volumes pours can be achieved.
