My buddy just got his pearl white car detailed it had major brake rust all over his car he took it to this detail ship, they sprayed this dark green or dark yellow liquid onto the car and worked it in lightly with a block sponge after that they ran it through their premium car wash that had rain x protector shield, clear coat protectant, mild wax protectant after it came out all brake rust was gone was asmazing and then they buffed a light coat of Meguiars sealant on their looks shiny as hell but at some angles you see the spider web or swirls on top of the shine what do you think that is caused by? thanks in advance.
 
Any automatic car wash is just a terrible idea if somebody is serious about their paint. Swirls are there from anything that has ever touched the paint, unless it was clean microfiber. There's a good chance the cleaner was Simple Green in some water - plenty of people use that to clean the engine bay for the same reasons it works on brake dust. It would also remove all wax, so the fact that the shop put a cleanser on the car then charged for "clear coat protection" (whatever that is) and "mild wax protection" (another mystery), THEN sealed it... wrong order. Also I like rain-x on my windshield, not so much on my paint.

The swirls can be removed with a polish. This can be done by hand, but somebody that knows what they are doing with a machine polisher can kick some serious swirl-ass. Remove swirls with polishing, then use a sealant, then - you gotta protect the surface with wax. Always always wax to protect the paint. The idea is that dust and contaminants get stuck on the wax - not in the surface of the paint. If there is no wax, anything that touches the surface can be causing swirls. Expect to pay a professional between $150 and $300 for a righteous detail - wash, machine polish, swirl remover, sealant and wax. It's expensive because to do it right - it takes most of the day. There can be several steps to machine polishing, depending on how bad the swirls are.

The "spider web" cracks concern me - would those be visible only on non-metal body panels? Spiderwebs are usually cracks in either the clear coat or the base coat. On non-metal panels like bumpers, it could be because of an impact - something hit the panel or the car hit something. On metal panels, I'd guess bad paint preparation at the factory or aftermarket paint job.
 
I have a spider web crack on my bumper...it sucks to look at! not really ready to put in the money to get it all fixed up though!

my experience is spider web cracks especially on bumpers are from bad paint jobs.....really called stress cracks. Bumper would need to be repainted.
 
There is a polymer wax product called wizard final cut. It is safe for all paints and clear coats, it will not leave any white residue and will take out swirl marks, spots on any color paint. For those of you that have black cars this is a must have, no more swirl marks. Buy it and I guarantee you will never use anything else again!
 
Rust is embedded iron particles and there are specialty products (Iron-X, etc) that dissolve the iron out of the paint which maybe what was done on this car. They typically turn purple when applied to surfaces with embedded iron particles and they are acid based. Otherwise it sounds like a typical autowash shop where the term "Detailing" is stretched to the limits of useability... It does not sound like a proper polish was applied and frankly I would not want any volume based "detailer" to ever attempt to "polish" my car. A simple orbital buff with a decent one step polish should handle a majority of the swirls, but if not a professional detailer can determine how much cutting is needed to correct any flaws. Keyword, "professional".

The "spider webs" sound like micro scratches from a dirty polish pad on a buffer which is par for the course at a volume based car wash. I've seen some of these guys set a buffer down on the concrete with the pad on the ground, then pick it back up and go to work... Gives me chills thinking about it...
 
Guys I don't think he means "spiderweb cracks". I believe he is referring to the swirl marks on his car that a lot of detailer's call spider webs not spiderweb cracks. The reason being is that swirl marks in sunlight almost look like a spiders web which are ultra fine swirl pattern scratches from being too abrassive with the paint. It has nothing to do with being cracked.

Spiderweb cracks are usually stress cracks put into a panel on the car and not scratches which is what the original poster is talking about.
 
spiderweb cracks usually occur when u bump into a round object. For instance a pole.
