since we are on the primer convo.
do i use etch primer for the front bumper??

No. You will want to use the appropriate adhesion promoter on any areas that have bare plastic though. Each paint company has their own which will correspond to their own material. Etch primer is for treating bare metal before applying high-build.

Also, for the plastic bumpers (or any flexible plastics) you should be using a flex additive on ANY material applied to the bumper, as well as flexed fillers - not simple putty/bondo as it will not flex with the bumper material.

i have one of those Tii rubber tyoe wings to. what about that?? what kind of primer?? i am going to ask the people where i get my paint what to use for a primer and what to add in the paint but id like other opinions also.

To be honest, the typ of plastic in the wing escapes me right now but I think its ridigd stuff........don't quote me on that though.

Here's the test though, snip a small piece of the plastic from an area where it isn't noticable (hard to do on the spoiler - easy on a bumper) and drop it in a cup of water. If it sinks - you don't need adhesion promotor. Best way to remember is:
If its a floater, use the promoter
Seems crude, but thats what you do. There's too many types of plastics out there to get into specifics and this test was taught to me at a Lord Fusor rigid/flexible plastic repair certification course in 2004, so if you've got questions, email them

To be completely honest, my opinion is biased because of the amount of disasters I see people create in their driveways and garage's. But my advice would be if you aren't entirely comfortable with it - leave it to the pros. There's still much you can do yourself to learn and save money along the way.

That being said, if you're the paitent type, you can probably make out alright. I'd recommend finding a shop in your area that you can get to know. Usually a lot of small shops will sell material to the odd guy (some sandpaper, primer etc) and you can usually pick their brains for some guidance and tips.

But I'd start by taking your car by a shop and having an estimate done. Not for an actual price (but hey, ya never know) but to squeeze out of the estimator what the condition of the car is. I.e. whether its had a few areas sprayed, find old filled/repaired areas, trouble spots etc. That will give you a good idea of where you need to strip, what you don't, etc. then go from there...

Car: too many ...

The thing about primer is that it will soak up water. So if the car gets rained on it will start rusting from underneath. Its actually a really bad idea for a daily driven car. But if you must do it, you can spray clear over the primer and it will be protected from rust. If you really want a cheap paintjob and you're considering primer, you should look into that new chalkboard spray. Its more fun because you can have friends draw on it with chalk (and then erase or whatever lol). In any event, I would just save the $$ until you have enough for a real paintjob, Macco or not ...

Anjiru,
I know from first hand experience that you can drive a car for over two years in primer. IT HAS to be a two part epoxy primer though. Epoxy primer is similar to a sealer it is ent to take sanding and body work and with stand the elements. I used Nasson(Dupont) epoxy primer and it is a greenish grey color however it is very hard. I suggest that you use PPG DP Series primer. I put on two coats of primer and it lasted two years and then I painted it. IMO do NOT sand the primer until you are 100% sure you are going to get it painted. I made the mistake of sanding it before I was ready and drove around for two years with a car ready to paint. However two years of wear and the primer became pourous and hard to wash and sand when I finally gat ready to paint it. So spray two coats on it and leave it until your baby is ready to be squirted.Here is a pic of my baby before I squirted her....

my 2 cents worth....


Yes I agree with all of these comments to some degree. As a Automotive painted, I don't recommend driving the car for a few years in primer ( even though we have all driven them this way ) then just scuffing and shooting the car. Primers either catalized or not, can be used as a sealer or a filler but these surfaces are not designed as topcoats. They have no longevity to the harmful rays of the sun or the different kinds of weather we all see all over the world. Primers do soak up water, causing rust under your finish, If your going to spend the money Id have to agree with the CrazyHawaiian, save your money and get a real paint job in the future. If nothing else save the money, prime it yourself & then let Maaco paint is as soon after as you can. Bad paint is better than no paint..... Good Luck, and the most important thing is do what makes you happy, If you want primer, then PRIME IT...

I am not tring to be argumentative but Anjiru has already stated he does nothave the money for paint at this moment. The question I need to know is Anjiru is you car able to be driven as is without having to worry about rust? If so drive it. If it need sto be primered then primer it. You can go to Maaco and get a cheap( in price and qaulity) squirt. Only problem. The paint is watered down as well as the clear so it will not last long. They spray one coat of paint, if some spots are not covered too bad, followed by one coat of clear before the paint has had a chance to dry. So your clear looks distorted and your car looks terrible. essentially you would save time, money and headaches by just priming it and waiting to get YOUR paint job the way you mant it. I did it and all I did was scuff, reprime( a sealer so it needed no sanding), squirt and clear and my baby is gorgeous. also theguy who painted my car has been doing body work and painting for almost 20 years.

Do what you have to do and what makes you happy.Good Luck.

in my opinion, it should only be primered as long as it takes to dry and get the new paint on.....

primer isnt a fashion statement, its a sign of progression, dont half *** it.

since it absorbes water, its probably best to primer it for a day...max, then repaint it....

give it long enough to cure...

87 z28 if you will read in one of my earlier posts the guy who helped me paint it has been painting for over 16 years. My dad has also been painting for over 20 years so I dont think my own father would screw me over and give me the shaft on a paint job. It took three days to paint the car and the fiest day was prep work alone. The paint will last as long as it is good paint and not wal mart paint. If you actually take the time to prep the car for paint, as i did, the paint will last. Hope that explains why my paint will last even though she was in primer for two years.,

How long can you leave primer unpainted on a car?

They also hide and prevent rust or corrosion. What is this? Most primers should sit on a car for around 24 hours before applying the base coat of paint. Some primers may dry in as little as 30 minutes, but experts say to apply the primer 24 hours before painting for the best results.

Is it okay to leave primer unpainted?

Primer can generally be left unpainted for no more than 30 days. If you wait too long, you will not be able to paint directly on the primer and will need to re-prime the wall. This is because it will begin to break down immediately after drying, and dust or other debris will accumulate.

How long can you leave oil primer unpainted?

Some primers can be painted on sooner around three to four hours after drying, though. Latex primer is different, this can stay unpainted for up to thirty days. And oil-based primers can last for up to fourteen days without being painted.

Do you have to paint over primer?

Depending on how strong or bold the previous color is, it may be necessary to apply more than one coat of primer. However, it is not necessary to over apply the primer with so many coats. As long as the primer applies uniformly over the previous color, then one or two coats should be sufficient.
