What's Wrong With These Alloys?

Bought off Fleabay, looked ok in the ad, but in reality the metal looks very 'grainy'...how to get them smooth n shiny?

Sandblasted then painted?

At a guess they have been refurbished, badly, Blasted with course media, hence the pitting,

Get them refurbished properly and it will solve the problem.

To achieve smooth & shiny on those wheels they will need stripping back to bare metal before being repainted.

You could spend ages with 1000grit & finer sandpaper down to 2000-3000 grit followed by polishing the remaining paint but the surface looks so dimpled I'd be amazed if there is enough paint to achieve a smooth enough surface.

Arundel.

The quotes I've had vary from "we can't do anything with those" to £425

Unfortunately the usual acid dip and repaint refurb places won’t want to put the labour in refinishing those

Not sure why not, high build powder primer would smooth that out no problem at all.
