Guys...

I sprayed my car 3 months ago, replacing new bonnet as paint sifu said if it's already rusted then he can't guaranteed that it won't come out again... so i took in his advice, and change a after market wira hood for rm200, but one month ago, it's starter to have those pimple things came out, and recently it's spreading and got around 5~6 pimples on my hood, i bring my car back to pain sifu and he said he never face this kind of problem before...
The inner side hood was stuffed...
