yo i had the same problem my brother lefy my blasty in the rain for about a year and a half before i brought her in fixed her and gave her a HOME ha but yeah my brother had a nice new chrome fmf.. when i got the thing it was brown.. what i did was i took steal wool and glass cleaner and i just sprayed to lubercate and i steal wooled the hell out of the thing.. i mean the tight packed steak wool.. um but yeah.. it never shined but at least the rust was gone thus making its life longer... sooo when ithen did is i bought thermal flat black spray paint.. the kind ppl use to paint old grills. anyway its great tho people with stock blasters think its stock and its not so when i race them and win they scratch there head and im like yeahhh shes allll stock i gues u just arent as good a rider as me.. hahahah its greaaat people feel like they just got sh*t on and they let it get to there head and they ride like 40 feet behind the rest of the day hahahahah but yes just do that its alot easier and looks better, remember to use layers dont put it on thick and dont touch it until theres at least 3 layers on it. and DONT forget to rejet ur stock carb to 240!
