im not gonna lie, thats super cheap. i could spend 6 hours polishing one panel and still not have it perfect.
for me to polish with a orbital polisher, and do a single step polish with a medium cut pad, i charge at least 110 for a honda fit sized car, and it takes about 5 hours. it also depends on the paint. some clearcoat is harder to work with, like mercedes. the first mercedes i ever did kicked my ass. cermiclear is not fun when you dont have the right polishes.
what i charge people is still considered cheap, but in order to gather more business i have to stay competitive. my business is all word of mouth. so lower prices plus quality work has yielded me good results so far.
