Decals - Clear coat & Sanding grit

I'm wanting to apply some decals to the body of my truck. How do you clear coat with sanding for the auto body? Sand paper grit to use? Very fine: 220-240? Extra Fine: 280-320?

thx,

I am not sure what your question is. You can apply decals over clear coat. If your wanting to sand to re-clear a panel you can use 800 grit. If you use courser grit, it may show through the clear when applied. Does this help?
