For door jams, drip rail, and fire wall I like to sand blast. You can get a 20-25 gallon blaster pretty cheap at harbor freight. Play sand from HD works well as a media if you strain the pebbles out. Keep the blaster away from larger flat panels like your hood because they can warp metal. If it’s thicker sheet metal like a cab floor support or has Intricate bends like door jams you can blast it, saves a lot of time rather than trying to sand in hard to reach areas.

Never use play sand or any sand in a blaster. Use blasting media made for that purpose, sand is silica based upwards of 90% so unless you have a great filtration system not just a mask but pure filtered air you will inhale some as will everyone down wind of your blasting . Why take the risk when black beauty is like 8 bucks and contains far less than 1% free silica.

A lot of people say they sell it in the store for kids to play in so it must be safe . Sure it's safe in its unaltered state. But once you use it in a blaster you are cracking down the grains to powder that will stay on you and everything around you for a while. Ever look at the plume around guys using a blaster? To save 40 or 50 bucks isnt worth it .

I use black beauty and grushed glass for blasting .
