Thanks for the replies , i will be letting them know about the sanding bit , if they choose not to have it done will it cause problems for them in future ?I am aware of the sanding aspect and i assume its done once the drive has dried off ?Also what really should i charge for a job like that , just the washing side ?Thanks Rich
I would a use a lance for a job like this and spray art 45 degree to the surface my price would be 4-5 quid a metre depending on the dirty is was. I think re sanding is a good extra income if it needs it.
