Undercoating aerosol

I've had good luck with SEM but it was for a shutz gun, so I'm not sure if their aerosol is the same or not. I know the OP was trying to save money on the "budget" hellcat swap but if you are going that far, rent or borrow a compressor and use Raptor. That is all I use anymore. You can get a factory texture but the stuff is totally impervious to chemicals.
