Thank you!
Problem solved, it is a bit difficult to find Pontiac caps in Finland anyway, so I did a little search and find out that
Honda Civic caps is what many people have used and those I found from the first shop I asked. I found another finnish language thread where they had covered Honda caps with aluminium tape instead on painting them, so I decide to do same and add Fierostore stickers which I bought just in case last year when ordered ball joints and other stuff.
