Pleeeeeeease help!! I have a Little Tikes child's playhouse for my grandson. It was bought from my neighbor. It has oodles of spray paint on it. I want to remove this paint. I have tried using Krud Kutter, paint thinner - you name it - to no avail. The house is made out of a molded plastic. I am at my wit's end! I KNOW there is something out there - can anyone help? Many thanks!!
