I chatted with a body shop today (our BE was in to get the chassis alignment checked: it passed. The lady helping at the front desk called it adorable, and got a picture taken of her in it for her 8 year old son) regards corrosion around the beading, and he suggested spot sandblasting. Generic sandblasting does, indeed, Warp Panels (ask me why I know). But spot sandblasting is probably the most affordable approach to cleaning corrosion out of locations such as this. It's also a feasible 'at home' approach, unlike (sigh!) the laser method. Doug
