You can hold that Econo paint on the car for a long time, but only if you maintain it.
I'd recommend a very good sealant wax (KLASSE) and an AOI Cleaner... try and stay away from chemical/cleaner based wax. <--- That's actually good advice for any paint job to be honest.
I'm not sure if the less expensive jobs such as this one come as a base coat clear coat... just make sure to maintain it.
GL with everything.
