For over 10 years I have used two large pieces of acrylic acquired from Lowe's Hardware to place over Formula De/Formula D racetracks. The acrylic sheets keep the maps flat, protect the out of print maps, and permit overhead projector pens to be used to write on the gaming surface for debris, oil, and game notes.

Acrylic sheets are less durable than plexiglass but they are lighter in weight and fit in most non-cargo vehicles (i.e., cars smaller than pickups, SUVs, and vans).

I also have used my acrylic sheets for Car Wars maps. The acrylic sheets work well.

I use sticky tack for my counters for dropped weapons, debris, and other map effects. Make sure you remove sticky tack from your counters and maps right after gaming. Sticky tack often stains counters and maps if left on those paper items for an extended period of time. Sticky tack solves the slippery issue with counters and many playing surfaces.
