In theory you probably could get low observable characteristics with just materials alone if they were good enough, but that would be pretty impractical since you would have to literally plaster a plane with it everywhere. That said it’s also probably the case that the better and more general use your materials are the more you can relax some shaping aspects in your design for a target RCS. But overall it’s important to keep in mind that oftentimes a lot of the most powerful absorbers are mostly used to deal with hotspots or sensitive areas and aren’t as good for broad application. So in addition to shaping being more of the first order factor in lowering RCS, we need to discuss when and where a particular material is applied when looking at the efficacy of RAM.
Yep, good points. One example of general use of RAM to reduce RCS is the A-12 exhaust channel, recalling from memory it’s basically fully comprised of RAM materials

The "Smart Eye" man-portable artillery reconnaissance and guidance system. It has two components: 1. The artillery reconnaissance kit used by forward observers, compact enough to be carried in a backpack (first image); 2. The artillery guidance terminal used to direct fire and program smart munitions (second image).

The forward observer, upon spotting the enemy, uses a tripod-mounted surveying instrument to acquire the satellite positioning coordinates of the enemy position. The coordinates are automatically beamed via satellite to the artillery guidance terminals, which are then used by the artillery troops to aim their guns and program satellite-guided artillery and mortar shells.

The system enables very fast reaction time. It takes less than a minute from acquiring the coordinates to firing the guns, and the accuracy is within 1/10 of a meter.
