Hi Pressure Cleaners Do Damage?

[Dingus]

Yeah, no way it will cause that kind of damage. I've used them on all my cars and never had any issues. Worst I've seen is a mates 32, which had paint lifting a little, hit it with the high pressure and blasted a chunk of paint off.

Paranoid OP should read the posts in the thread and take in the information. Seller was A. full of shit or B. didn't know what he was talking about. Almost every car detailer uses high pressure washers these days. The reason they don't dent is because water weighs bugger all and the impact is powerful, not torquey. Car panels flex anyway...and the ones that don't are too strong for water to cause a dent.

Case in point, buy a $100-$200 pressure washer from Bunnings, which is all you need for a car anyway...no need to even talk about industrial strength washers. Squirt your hand with it from 50cm away and discover that it has less strength to it than your garden hose when on full blast. I usually wash my panels off with the gun about 50-100cm away because that's where my nozzle attachment is most efficient at clearing suds from the car. At this distance it's softer than a shower. I've held it within 1cm before to remove bug stains and had no issues at all. It'll hurt your skin at this distance, won't hurt your paint unless you have underlying issues like cracked/chipped paint or rust beneath it...even then, the washing of the car with a sponge will do more damage than the pressure washer.

Thanks guys.

No harm in asking.

Birds pretty much summed it up

No harm in asking, no...it's just more respectful to make it look like you've taken in what other people have said
