car wash in north dallas

[youplaboom]

Hey guys,

Do you know any do-it-yourself car wash in north Dallas where I could wash / clay bar and wax my car ? (I don't have a garage)

Also do you know any place where I could check & adjust the tire pressure ?
I took a look at the pressurized air machine on a shell gas station but I could not see any gauge to read the air pressure ?!

As for the air, invest in a nice quality round face, analog dial...
