let someone else do it! is my first suggestion but if you choose to do it your self these are my tips from past experience. get someone else to do it ! OK make sure your compreser has enough cfm. to keep up to your blaster and you don't have any water in the system,next keep the sand flow off (if you don't have a valve install one) when you plug in the air,hold the hose away from you and the vehicle then gradually turn the sand on you will here the difference as it increases ,point your tip at the panel with one hand and increase flow with the other untill paint starts to come off don't open the sand all the way other wise the air just pours its onto the panel then on the ground very fast you need air preasure and lots of it and tape all your openings shut that stuff gets every were or you could get someone else to do it!
