The crew figures seem to be sticking very well to their magnets, fingers crossed, the next job was to fix some picnic items to a magnet-backed aluminium sheet. The materials to be bonded were aluminium, cotton fabric, epoxy putty and ceramics.
I got some Soudal Fix All Invisible High Tack and have just assembled the item, it has a very strange consistence, a stiff gel, but easy to spread and very tacky, it is clear and very easy to work cleanly, excess that squeezes out is easy to lift away with the point of a craft knife.
So far, very impressed, it will be interesting to see how it is after curing overnight.
