they are saying that he was buried at sea in lieu of the Muslim faith and so no country could fight for the right to the body. whether u want to believe that is solely up to you.i say if he's gone, let him be gone!
one tip on the airbrush subject: get in good with your local bodyshop if you want to try automotive paint! one thing though, alot of places are getting away from laquer paint. (states are starting to treat laquer like trans-fat in our food.)
i use both airbrush and spray cans. spraycans are fine if all your going to do are paintjobs but, if you want good detail with weathering or pinpoint areas, an airbrush is the only way to go.
