Chevy/GMC side molding

[Vince311]

I’m going to be building a Chevy Swb truck similar to the one in photo. I’ll be Using the snow plow gmc truck as a starting point. 
 

what is the best way to create the body molding? (As circled)

thanks!

It's going to ne very difficult to replicate the molding, due to the recessed area, but for the basic shape, see here:

 

You could create the molding with multiple pieces, spacing them properly as you adhere each piece to the body shell, but that recessed area might be too small in 1/25 scale to bother with, too.

That's actually a tough question, particularly if you are aiming for real accuracy. It could be done with double-etched stainless steel, where the partway down etch creates the channel that you'd have to fill with black paint (unless you were building a 1977, where that trim had yellow paint for that model year only). The rest of the etch would cut all the way down through the metal to give you the separate pieces you need. Problem is, you'd have to hire somebody to do the artwork and actual photoeching, which involves quite a bit of meticulous measuring to get it to fit on your model just right. I used to work at a nameplate manufacturer that also did aerospace quality photo etching, a person needs to calculate what amount of oversize the artwork needs to be to compensate for double etching relative to the thickness of the metal, since that involves eating away the outer edges of the metal twice.

I've wanted to build a '76 GMC Jimmy factory stock for quite some time in the High Sierra trim level, but the one barrier to accomplishing that project is how to do this exact kind of trim. In 24th scale, these would be really delicate pieces.

You can get pretty close using a couple sizes of plastistruct strips. 

Carefully glue the wider one on first with liquid cement, let it fully set for a day or two and glue the narrower one on.

Worked pretty good for me. 

I added the trim on the box to match the existing trim on the cab.

Thank you! Looks like super thin styrene strips. That could work. I think etching might be a bit to much. This should be fun

I used a combination of 1.5 and 2 mm half round Plastruct to create side trim on the Suburban. They also offer flat stripes that may better represent the side trim you're trying to make. The scale is such that the black colored stripe my not be visible anyway.
