Yup. Just an overlay job. Known as the "Poor Man's CF overlay".
Immersion printing is strictly for bling. It does not add strength to the part. Honestly, I don't even know how well it does at higher temps, like the ones found in an engine compartment, as I've never used the stuff.
I have to admit, just for little bling here and there (like on the inside of a car), this stuff is nice. Very little work involved as opposed to a CF overlay.
Molds are easier to work with once the mold is done, but realistically, they are used to make bigger CF stuff that needs to be strong. Suspension parts, wheels, drive shafts, intake components, body panels, reinforcing supports, stuff like that.
