Side sill should be covered under the body perforation / corrosion warranty. Don't remember the duration, but it significantly longer than the basic 3/36.
My 1996 GTS sill was....
Note, Don't know about early RT/10's but 1996 & most 1997 GTS sills will perforate. Only a question of when. The more you wash the car, the more rain it sees the sooner it will happen. If you want to prevent, carefully remove the sills, remove the insulation, clean and paint the inner sill with caliper paint, then attach a thin non-absorbent, high temp insulation like thermotec. Shiny side to the sill. This keeps the water absorbent factory insulation off the inner sill wall, where it will hold the moisture against it till it corrodes. Alternatively, you can purchase the newer all metal sill insulation from Dodge for about $300 if I remember correctly.
Better to prevent then utilize the warranty as the paint (at least Viper blue) seems difficult to match.
