Well first of all im new here and would like to introduce myself, Im into model cars and love building them. Well i've built only one tho and now im on too my second one. Here is the problem, I've messed up on my painting on my model, first i painted it with a white enamel paint and decided to change it so i painted it over with acrylic paint

and the painted started to crack and and leaving crack marks and now it looks horrifying

! I spent money on this model and was hoping there was a way i could strip off all the paint off and start from scratch again? You help and advice would be greatly appreciated.
Thanks in advance,
