    How about some suggestions/techniques for both cutting and filling square windows on the sides of car bodies. What tools do you use?

    Micro-Mark sells a 3/16" Corner Punch, #82394. Useful for windows no smaller than 3/16".

    Accurate placement is necessary. I have trouble with accurate placement so I punch slightly inside the opening desired then finish with a modelers knife. Scraping with the edge of a modelers knife helps to get the final square corners.

    When using that tool it is also important to pre-drill a hole slightly smaller than the window in the center. That way the scrap has a place to go when you punch with the corner tool. Otherwise you can deform the rest of the car side. I also start by making a template out of sheet brass for the window and use that to scribe the outline into the car side with a sharp stylus before cutting anything. It is a little extra work making a template but it can be used over and over again and helps make all your windows the same size.

    I have wondered if their punch would work on plastic sides. THanks for the info.

    I use the Universal Laser Systems M300, which cuts perfect holes in thermoplastic.

    [​IMG] And the M300 can be had, used, at about the same price as a dozen or so diesels. The Micro-Mark punch is slightly less.

    I couldn't find a price for a new M300. They must be sold out.

    The question was, "What do you use."

    That's what I use.

    Small metal square. Lots of sharp #11 blades. Measure twice cut once.

    I use 1/16" styrene. Most window holes have and inside frame that need to be removed making the opening slightly larger. The, as stated before...#11 xacto knife. The plug should be set even or slightly higher than the body. Too deep and it's aproblem. A little high can be sanded smooth...........Example

    Thanks Marty...I assume you use a styrene backing for the plugs? Gap filler Before sanding? Thanks again.
