Some suggestions from practices I've used on multi-day trips through bug country...

Basic maintenance includes using a "Sealant" compatible with matte paint to help protect the finish. Then before I leave... I use this product from Griots to help put a layer of protection over the body parts. Then, when I get to a point where I'm going to clean off the bug guts... a bucket of hot water... soak towels (many hotels/motels will give Bikers their old hand towels for cleaning bikes)... then lay the towels over the guts to soften... then gently wipe off.
