what is the air temp and the cabin top temp . is it in the sun. if it is bubbling after you spread it on then it is heating up from the surface temp being to high. try mixing it even thicker. also the thicker the easier it is to sand and the lighter in weight it is. if you mix it to the same consistancy every time it is easier to fair as there are no hard and soft spots. put it on a dry as you can thick a with one swipe and sand with 40 grit to shape until fair. then go over with the same consistancy and fill the holes then same with 100 grit. paint some epoxy high build primer or squeegy on some resin and wipe off excess with a cloth. this is just to fill the pin holes and sand to 240 for paint primer or gelcoat
