paint problem need help please

i was told to pour hot water on the paint and try washing it off. it felt like my nail could have scrathed it off bit i did not want to damage the clear. it looks like in the paint yet if i rub really hard with a clay bar it goes to just the clear. the hood roof and trunk are covered. very little on sides of car and it comes off very easy. feels and looks like cloudy little bubbles all over and the odd little brown spot of dirt is in it and even to get the brown spot out takes one heck of a lot of scrubbing with a clay bar. i was told that i cannot cut polish it out as all i am doing is mixing the contamination into the clear.
