Part 1 Creating contours ^^Begin by gluing styrene or whatever substrate you plan on using to the project. Shown here is styrene panel bonded to MP Starscreams hip junk. This will become a rear quarter panel for a MP Hot Rod project. ^^The factory part already had a flow that suited this project but needed to be widened and curved in specific areas. I begin by putting down a piece of 80 grit sticky back sandpaper to my desk top. I then sand the area down in a rocking motion to achieve a gradual curve. It's important to use long strokes and be sure not to press hard. Let the grit do the cutting. ^^I use the same technique on the other side of the panel. ^^Now cover the whole thing in filler. ^^Follow the same technique as before and round your panel out to your liking. Do not sand it all off, we're trying to create a larger, rounded body panel. ^^Side panel gets the same treatment. On this side, I rounded the lower quarter to curve inwards towards the rocker panels. ^^Wrapping a piece of sandpaper around my finger, I...... ^^....notch out a combination crown in the forward section of the quarter panel. This then needs to be worked into the other high crowns by sanding the curves lightly. ^^ The panel takes shape as so. I'll need to go in a put a quick skiff on the dark red area which is a low area then sand it out. ^^Always be sure to test fit your parts.
