Dad got all panicky when he found a bird poo stain on his new M3, he took out the 3m wax and adhesive remover and tried to rub it out, and we go back and look at the spot and it looks all "ripply", so what the heck happened

i have a black car, and ive left thats tuff to soak in for 30 min, and it didnt leavy any blemishes at all

what the heck happened? is it ruined?
