the greddy products are not very high quality, i wouldn't have the same expectations as i would of a nismo, top secret, or kenstyle product. anything made in china that is priced cheap (replicas, jp, extreme dimenions) is not going to be able to take the abuse of daily driving. a high quality frp kit will hold its form and paint very well. you have to figure if brands like nismo and kenstyle are good enough for the standards of nissan dealers in japan, it is good enough to handle the united states

 

My replia kenstyle sides have massive paint chipping on the bottoms. My urethane Nismo replica front has 1 or 2 spider webs from rocks, I suppose.
