	I'm re-modelling the bumpers and sideskirts with firbreglass and filler, just wondering on everyone's views on wet sanding vs dry for shaping/flatting down. Watching overhauling they seem to dry sand most of the time but american hotrod are often wet sanding. I did one side dry and it took forever, created lots of dust and paper kept clogging with old paint, the other I've started doing wet and it seems a lot quicker, quite messy (better than dusty) and a better finish. Obviously with it being wet it needs to dry out before any filler can be added so that's one disadvantage. Any other views on this?? Sorry for the boring question here's some amphibious vehicles (wet and dry, see what I did there )......

	I've got mixed feelings and have done both. For roughing out I always dry sand. If you use a good quality paper like Kingspor it's no more expensive but it doesn't clog up. Filler and primer are porous, so if you wet sand it soaks in and you end up with the filler and primer full of water. You need to let it dry out fully before you do anything else. Obviously, any steel underneath will have been exposed to water. If you spray onto damp filler and primer you'll trap the moisture underneath the paint and it'll come back to haunt you. That said, I would expect most classic cars were wet sanded; back in the celly days I was always taught to wet sand bodywork and I wet sanded my first car with no problems. It was painted with celly though, not 2K. Pretty sure my bodywork book said to wet sand primer as well ;D On the other hand I'd only consider flatting topcoat by wet sanding it. The dust is too fine to dry sand and you need the water and soap to take the debris away.
