It works also with Solarez, I've done it a couple of times with success. I use a clear plastic to create a mould to hold the Solarez. The clear plastic is attached above the repair in various location with masking tape. Expose to sun for 3+min and then remove the tape and sand it. Try to avoid using excess Solarez because it will be quite time consuming to sand it.
ok if you dont have the time to wait use SOLAREZ with UV cure.but its expensive and the most of the quantity to fill the mould is gonna be sanded away.in the other way BISON cost a few euros
