have you ever passed up a job because you did not think you would satisfy

great point about under-promising.

i never guarantee spot removal but it should look quite a bit better - those are the exact words i use. most do come out 100%, then you look great.

the opposite is also true: if you tell the Client that all spots will be gone - and then you can't remove 1 or 4 of them. now you look like a lamer
