So Vision managing director Glen Stapley is appealing for volunteers to join in the fun tomorrow.
''If you don't have a car that needs washing, and you like to get your shirt off, come and show us up.
''None of us are athletes. We're not show offs, but you just get into the spirit of it and do it.
''It's something we're quite happy to do to raise money for a good cause.''
Mr Stapley said it was a busy time for the company and many staff were unable to help this year.
He hoped to have about a dozen people washing cars after they were inundated with dirty cars last year.
''We had cars lined up along Portsmouth Dr There were dozens of cars waiting to be washed at times.''
Last year, the team managed to raise more than $2500 for the Otago Cancer Society's Relay for Life.
This year, cars would be washed for $5 again and it was hoped to raise a similar amount, he said.
The men will be putting modesty aside and flaunting their physiques from 9.30am until 2.30pm tomorrow, in the Vision car park opposite the Harbour Molars. If the weather was poor, it would be postponed until the following weekend, he said.
