What degree tip for a 2800psi washer? Foam lance?

[flugufrelsarinn]

I bought a 2800 psi 2.5 GPM pressure washer for my deck, siding and driveway. I figured I can use it for my car too.

What degree tip should I use on it so I don't harm my paint?

Is this enough PSI to use a foam lance?

I use the white one. Sometimes I use the yellow one under the fenders.

How close do you hold the tip to the paint?

i think the safe pressure is around 1700psi , better ask the manufacturer or the tip supply.
