Do you add a lacquer over you finished CF part ?

I wonder, maybe a stupide question but, do the CF parts we buy have received a lacquer coat on top of the gel coat ?

Is it useful ? Does it render better ? Does it add extra protection over the time (compared to gel coat) ?

Or, once you're finished with your part curing, it's over ?

high solids automotive paint would be best, as it has high UV protection in it already. but they are made to cross link with their respective brand's base coat( the color in base coat/clear coat systems), so they may eventually peel. be sure to carefully abrade the surface, i suggest a gray scotch brite pad and
something like comet household cleaner. it is a dry powder and is for scrubbing(with water added) bathtubs and sink basins and will take the gloss off and not expose the carbon fibers themselves. plus side is it cleans the parts very good but you must be crazy with the final clean. comet leaves a chalky haze when dry so be very sure you get the surface totally clean.
