Pricing. System Clenz WSM. Help

[James.B8]

Hi all,

Looking to get my S3 booked in for a detail.

Wondering if anyone can help me out on price. Job I've been quoted for is going to take 3 days.
Going for the following which I copied from the email:
Enhancement detail to remove around 70% of surface defects £450 (2 days)
Gtechniq Crystal Serum (7 year guarantee) £300 (1 day)

And he said he'd coat the wheels in the serum for free. Also he's wanting a £200 deposit.

Thanks in advance,

James.
