por15 is one of the best tank sealers, that money can buy
use it in a well ventilated area, close the holes with duct tape, poor it inside, close the cup and SLOWLY agitate, in order not to make bubbles inside
at fist, it is like silver metal car paint and as the time goes dy, it flows like honey and after an hour or so, it turns to skin
you sould pay attention to aplly it all over the fuel tank, inside, to leave no place untreated and to remove it before it starts to turn to skin
this is how it looks like after four or five houres
