Hello! I was parked under a tree 2 weeks ago and these red berries dropped and splatted all over the hood. I tried hydrogen peroxide, alcohol, some sap remover and dishwashing soap and scratching it off but its not coming off.

Help?

Knowing the condition of the paint, and the color and year of the vehicle might be helpful.

Is there any contamination on the surface, or is it simply discolored?

If there's berry particles on the surface, try a detailing clay. If it's stained, try a polish or (use with caution) an all purpose cleaner or dare I suggest some diluted bleach with a cotton swab -- have some rinsing suds handy.
