paint problem need help please

I had the scamp painted aprox 7 months ago, it sat in my carport for 4 1/2 months and looked perfect. we pushed it outside to build a new fence. 2 1/2 months later we pushed it back in and there is a textured feeling to the hood,roof and trunk. nothing is taking it off, if i clay bar the same spot for 15 min aprox. 2"x2" i can make it go away.I think it is tree sap and dust when i take a kettle of water and pour it on, the area gets soft where it feels like i can dig my nail into it.Any ideas on how to get rid of this without wrecking my new paint job? even specs of dirt take 15 min to rub out with the clay bar. i have tried hand soap,keen flo tumbler, auto wash.I have not tried denatured alcohol as I cannot find up here. any help would be greatly appreciated.
