paint problem need help please

I think it is sap. The are that I was able to dig my finger nail into was what I believe to be the sap after hot water. I have tried many ideas to get it off, it is all over the top of the car and has hardened.(this is what I think) denatured alcohol I want to try but I do not think I can get it here in Canada? goof off heavy duty I will try if I can find it. if it was solvent pop would a clay bar with a hell of a lot of force be able to take it out?
