What are some of you doing to get epoxy inside of rocker panels and frames? My thoughts are to blast inside, treat with wet ospho, flush w/water, dry, scuff and Spray. There a better meathod here too? Thanks
 
We use a setup that was originally designed for cavity wax application. Not sure how you are going to scuff anything that is boxed in.
 
Sem has a kit that uses the Walcom gun that SPI sells for bedliner. It comes with the gun, a 36" wand with tip and a quart of inner rocker rust preventative.

Throw away the sem rust proof and use epoxy instead. Works well for me.
