as i've said before, this beetle is one hell of a survivour! and the surpises under the surface are amazing.
if your arms are tired try fabricating or buying a orbital/rotating polisher which could really speed up the process. I've also used glasurit on my 1303 but i did it by hand as i didn't want to overheat the clearcoat (which can severely damage it).
i can't wait to see this car in person.
