Hey Andy , What about a new box which i thought you got  when you got the machine? And have a full decal made , so don"t rub it back yet! Get some good side on photos and i will speak to Steve my slack arse signwriter! Chip board is bad!! You fix one spot then another part breaks off , You can seal it but this expands it even more and you will never get a good flat surface and would look like shite no matter what you do! i would burn it when you get it sorted,
