Just Pressure Washed Through my Clearcoat.....Aaarghhhh

My modern daily driver had a clear bra on the bonnet and mirrors to protect against stone chips

I didn't like the look of it so I removed it

Unfortunately, is doesn't protect against stupidity

Whislt washing the car after removal there were a couple of patches of glue still on the paint

I got these off with my pressure washer

I'm happy with my pressure washers performace......it removed some of the clearcoat too

I've been to the local body shop, and they've said it can't be repaired, blah blah.....

I know it can be repaired, can I do it myself with rattle can clear, or do I need to get a different body shop?

You didn't say if the bascolor might be affected. Is it clear only?

If it is, then what they could be talking about is the fact that you have some sort of adhesion problem. That means that if the whole car has that problem... the old paint needs to come off. :-(

The basecoat is perfect

The car is an '01 911 Turbo with original paint

I just had the pressure washer way too close (using it to remove the glue) and it took some clear coat off

They said you can't blend clearcoat into a spot repair, that there would be loads of overspray, and that it would quickly fail

Personally, I think I could mask it and rattle can it - but I've never done any painting before, so I need educating

You can do a blend but there is the need of good skills to do it so the repair does not show. the new clear is likely to have a bit of difference in the gloss as compared to the old so the repair shows..buffing can solve the problem..find another shop that does repairs on those cars \\

Thanks

I'll post some pictures later so you can see the damage

There's a circular spot on the front bumper, and quite a bit missing on the wing mirror

I don't think they're big jobs

The bumper is only a small patch, and if need be the mirror could be sanded right back

What they told you is correct, (Blah, blah) you can't spot clear in the middle of the hood and have it turn out and last, blah blah.

If the clear has came off and left the base coat intact, it is likely going to de-laminate because the clear isn't attached to the base properly or it woudln't have came off! blah blah.

If you spoted the clear over that it will VERY likely life with the solvent getting under the clear that isn't stuck to the basecoat! blah blah

To repair it the entire hood properly it needs to be painted (at least at the damaged spot) and the whole thing cleared at the very least. blah blah

The same with the mirror and the bumper. blah blah

Your pressure washer didn't blow off good clear, that wouldn't happen. It blew off clear that was ready to fail anyway.

So yes, it isn't a quick fix, sorry to tell you, blah blah.

a pressure washer can cut through paint no problem as long as its a quality unit.

with a 01 911 in the driveway i think this guy may also have a quality pressure washer.

i highly doubt there is a issue with the paint on a 01 Porsche.

i would have it fixed by a well recommended shop with plenty of references

Any shop doing quality work is going to clear that entire hood, PERIOD. The original poster wants to repair it with a rattle can, I doubt he would spend the money on super high pressure washer. And if he is complaining the way he did about the body shop I have to assume they told him it needs to be completely cleared which it does and he didn't want to hear it.

Without more info, is it a repaint for instance we have no idea how big it is, where it is on the hood, etc. But realistically ANY damage that needs spraying on any single panel gets the panel completely cleared, if it is being done correctly.

Thanks for the replies everybody
It's very much appreciated

As I said at the start, I don't know about painting
I wasn't trying to be cheap with the rattle cans, I'm just uneducated

But - we are all someone elses idiot
I may not know about painting, but I am here to learn

Thanks for taking time to reply Brian
It wasn't that I didn't want to hear what the guy at the bodyshop had to say
It was just that he had a bad attitude
He wasn't rude, but everything was too much trouble
It seemed like he wasn't interested in the work regardless of whether it were a big or a small job

The guy that does my detailing said the car has very good paint, and has never been touched (obviously can't comment on adhesion)
But I wouldnt have thought the manufacturer would take short cuts here

If it needs stripping and starting again, then so be it
It only looks minor to me - but, as stated, I don't actually know what I'm talking about when it cones to paint

With regards to my pressure washer
I own a Karcher HDS550C
It cost a little under 2,000 (English money) and it's a hot water blasting beast
The damn thing is near half the size of the car

I know 2 stage is the most popular paint now but I think it's weak. I have had a couple base coat/cleat coat paint jobs and it seemed very delicate. I backed my pickup up to a bank to load a 4 wheeler and it took all the paint off the edge just from the tailgate touching the dirt bank.

1. Don't pressure wash your car, hand wash it
2. Clear coat can't be reapplied to damaged base (color coat) Once clear comes off base paint needs to be sanded and another 2 coats of base need to be put on before reapplying clear coat.

I spoke too soon. If it is factory paint, then the pressure probably just exceeded what it will stand up to.

Contact the dealership and see who does their repairs. That might be a good place to start, since they would be more familiar with how to repair that particular paint than others.
