I have just googled this firm and found this reply on a Range Rover forum. I don't doubt the credibility of this company, but I guess you pay your money and make your choice.
'RIMSTOCK/RIMFURBISH Do Not Use
Just a heads up for everyone.
I sent my 20" supercharger alloys for refurb at
Rimfurbish 2 months ago. I went to them after seeing a link on here which I was very impressed with.
I decided to have my alloys shadow chromed and was told it would take 7 working days.
I went upto Birmingham to collect them about 3 weeks later. On the way up I had a few calls from the manager Matt Ball saying they had a couple of problems with them. There was an imperfection on two of them which meant they decided to respray them and hoped to still put them on the car that day. I was due to take the car down to spain the next day so had a tight schedule.
The two they had resprayed were a much lighter colour. I had no option but to have them put on the car. I was told that they had another set of my wheels in stock which would be shadow chromed and sent to me in Spain. I would then send my wheels back to them.
I good solution I thought, but over the last month I have been fobbed off everytime I contact them and am not actually sure they will fulfill their obligations.
I am thinking about contacting Birmingham trading standards.'
