I was at a car show this weekend and saw several beautifully painted VW bugs from the 1960's. It got me thinking-how do you block "flat" a wildly curved surface? There isn't a straight panel on those cars. I have the longer Durablocks, and I know they are flexible, but I just don't see how the sand paper would even stay attached to the block. Obviously this applies to cars from the 30's and 40's as well. What do you guys who do this for a living do when you want top quality paint on a curvy car?

Everyone probably has their own particular technique, but I like to back
the sandpaper with a sponge when sanding curves. Harder sponges for slighter curves, softer sponges for the more pronounced curves. "If you can't move it, paint it." - U.S. Army

But won't the shortness of a sponge make it impossible to get a flat surface? Or, if something is really curvy, does it even really matter? Maybe your eye can't see waves in a wavy surface anyway? |
I use the Durablock round sanding block for curves.
That and their teardrop shaped block are the only ones I use. 1968 Coronet R/T

I have what is called a dual density pad for that type of sanding to back up my paper. Gray side is softer foam and the black side is high density stiffer stuff. It is indeed harder for the eye to lock in on the "straightness" or flatness of a coating with no points of reference like that curvy VW surface....

Dual Density Pad!
So that's what they call it? I have two or three of them but never they had such a techie and official sounding name. 1968 Coronet R/T

Yep, first saw them in wood shops almost 40 years ago then noticed guys in old car books were using them on fenders. Furniture is so curvy they're perfect.
