My plan would be:
1) get new stickers under warranty if possible. Don’t put them on and save them for when you sell the bike so you can bling it up then for a quick sale.
2) Get onto ringmaster and get new sticker kit. I’ve had ringmaster on my bike for 3 years so far. They are good quality. I even put them on myself and they still worked.
3) Don’t ride your bike without stickers. Scratched plastics look shit and once scratched you can’t just hide the scratches with a sticker. The sticker won’t stick very well to a scratched surface and it will look lumpy if the scratches are deep. I’m pretty sure stickers are cheaper than new plastics.
