Are IPA and mineral spirits safe for clear coat?

I'm not comfortable using either but really afraid of mineral spirits and specially soaking tree sap with it for some minutes.
Are they really safe for clearcoat? Anyone has seen collateral damage of using them?

In short they are safe

The more acute element of risk in cleaning, however, is that of expansion of the paint through sorption of solvent. The polymerised urethanes dried oil network may not be truly soluble, but the polymer network may expand by sorption of solvent or concentrated alcohol molecules and silicone.
Depending on the degree of expansion, the paint will be more or less softened and its capacity to bind the pigment particles may be affected. In the swollen condition, there is a risk that pigment may be removed from the paint through the mechanical (friction) action of a foam pad.

Yes, the film build may swell temporarily, but once they evaporate the paint goes back to it intended and resistant state.
All of my testing data, by approved protocals, from the USA Big Three show the same as I have posted.
