:mad: My car is in terrible need of a paint job. The tard who had it before me was obviously not liked very much, and I have some nice key marks down the side and on the hatch to prove it. the ones on the passenger side door are pretty bad...and they started rusting before I got the car. What can I do about this... is it going to be harder to paint?? Also, whats your guys's opinion of maaco paint jobs?? I've heard mixed reviews... one friend got an excellent job done, with no overspray, but I've heard some not-so-nice things about the quality of the work and overspray problems from others. They said get no overspray in writing... should I be worried?? ALSO. What does wet- sanding do? will it make the car more shiny? Remember here that I AM a girl, and as yet do not know ALL that much about stuff like this.... as I said *YET*. Thanks you guys, you've all bee SO helpful!

maaco=crap, a waste of your moneyif i were you, ask car people/perf car shops if they can recommend a good auto body shop that can take care of your problems. they usually know of a lot of places. If you go to an autobody shop, ask to see their completed vehicles, ask what kind of paint they use, about how long they bake the cars, and only go for a free estimate. explain your problems, what you want done and be smart/reasonable about it--that way they assume you know what your'e talking about.

As you, i do have light rust on my car, mostly in spots here and there that more than likely resulted from the crappy paint job that was done on the passenger side of the car (i believe my car was in a accident on that side). Wet sanding is a much better method than dry sanding. It's done by the *better* auto body shops. it will smooth out a lot of imperfections. It's mandatory. There will have to be more work, on account of the rust, but as long as it hasn't eaten thru the sheetmetal yet, then sanding it down to the bare metal is what is required. Also, you have a hatcback, removal of the stock spoiler (if you have one) will be necessary to get to any unseen rust. fastbacks tend to have a rusty hatch issue.

Like i said, ask around, and forget about Maaco. They are not consistent enough to risk taking your car there, 'you get what you pay for' --you know? any paint shop that doesn't take off the weather stripping, emblems or paint the door jams is a crappy shop to me. check the internet to see what the best paints are, i hear dupont is one of the best..there are many other kinds that give different results.

and please don't mention your gender as a way of undermining yourself. Everyone is new to something at one point in time. Doing your own research, car work, and talking to people with more knowledge is all you have to do to fix that! :D

First things First, Lets talk about Maaco's way of painting vehicles. They Do not prep the car for a paint (i.e. strip, media blast, and wet sand) they just use a cleaning agent to clean any oils and chemicals off the paint, then they apply a Bonding agent to allow the new paint to bond to the old, and then they spray. If they do a good spray job, then, yes it will look good/great, but the bonding agent typically allows for a 3-4 year hold, and then once again your car's paint will probably start to crack and chip. This method typically costs $200-$400. You will get mixed ffedback on Maaco, because that exactly how the cars turned out, some are lucky and get a descent paint job, and some get aboslute crap. I'd agree with skydragoness on this one, stay far away.

A good autobody shop if painting a whole car, remove all weather stipping, door handles, embles, winshild wipers, squirts, etc. then will media/sand blast down to metal, mask any parts of the vehicle that aren't to be painted, apply a primer coat, wet sand the primer coat (this process is to raise the very small grains in the primer so that the paint will adhere to the car), apply 3-4 coats of paint, then apply 2-4 coats of clear coat, and once dried/baked, wet sand/buff the clear coat. Again, if done right, and paint job taken care of/protected, then their shouldn't be a need to do the process again. Of course, this method usually starts at $1,500-$2,500 and can go considerably higher if you want specific/special paints.

DuPont is indeed a very good paint, and so is House of Kolor, these are the only paints I will use anymore.Hope this helps, If you have any more specific questions please ask.
