Heck I'm 52 and delving into the DIY jeep painting!
I started long ago with my old YJ, and camo'd her up, loads of fun!
Now with my TJ-L, I'm about to treat the frame & under the tub. then next Spring I'll do the body ( Lusterless Earth Yellow Mil-Spec paint ) with 33 gallon compressor with what ever spray device that's appropriate for the paint that I'm spraying!
TA with the knowledge you'll gain from the web and here on the JF, or other forums you'll be ready for your painting endeavor!
Now select the appropriate music and start taping off!!
Enjoy and keep us posted!
