One thing I have noticed is it appears everybody is assuming that the inside of your cab is down to bare metal if it still has its original paint it needs to be sanded and scuffed prior to The Epoxie primer but if the inside of your cab is in good condition and you don't have bare metal showing after scuffing you could just use a sealer and then paint but if you have to go with Epoxie primer you have a window of about five days to apply your hi build primer so you have a chemical bond after five days you would have to re-scuff the primer so you have a mechanical bondfor your high build these are just basic rules of painting you should always read the labels and talk to the paint technician where you buy your paint and primer from
