Rated 5 out of 5 by RobW from Great Overlaminate Oraguard 290 is an excellent product: UV stable, conforms to vehicle contours, easy to apply. We use this product with a variety of substrates like MDO, aluminum and composite signs, and decals. One thing to note is that this product, once exposed to sunshine and warm temperatures, will draw itself down onto the substrate creating a optically clear finish.
