how do YOU paint cars, and what are the results?
The reason i ask this is because i'm going to paint my car this summer and have researched auto painting, which revealed different ways to paint. Some spray on light coats without sanding in between, and others wet sand between each coat (or at least scuff it with something). the main concerns are durability (ie. preventing paint chipping) and smoothness (no orange peel). fading, as i understand, is a result of paint quality, so i guess theres no discussion about that.
car painting tips (part 2?)
Just make sure you mix you paint right , keep you hand level with the car body lines ect. use correct psi for gun and paint.
Also what kinda paint system are you using basecoat/clearcoat systemor just a single stage paint.what kinda paint spayer do you have

i plan to use base coat and clear. My spray gun is not HVLP gravity fed. it is pretty old school looking, with a separate canister for the paint that is pushed up into the spray gun. There are adjustments for air/paint mixture. I have a decent sized air compressor so i'm not worried about have a constant supply of air. I'm going to primer my whole car first so i figure i'd experiment with that stage. My goal is to go through the entire paint process on the headlight cover first. i figure if i mess up a minimal amount of paint will be wasted. Also it's a small piece so i can easily sand the messed up paint off. if it turns out well the first time..i can just put it on the car. I've seen paint jobs that look amazing from the garage. I was told there are a few chemicals i'll need to mix into the paint before i spray it-something to make the paint dry more flexible? So should i wetsand between light coats or just spray light coats one after another without sanding? 180fan told me to use something to scuff the paint after each layer. any other suggestions/tips?
Your spayer Should Do The Job, You Only need to add a felx agent to the paint when your painting plastic parts such as the bumbers. When Spaying your basecoats your should not need to wet sand in between coats but you can if you see any drips, dirt, hair, ect. in the base coat you only need to scuff the paint in beetween coats in they are so far apart each other such as a coulple of hours. when spaying your basecoat start with a drop coat that is very light just so the next coats have somthing to stick tothe spay another coat to hide your primer wait ten mins and add coats as necessary.

could you clarify this? thanks! Also, is spraying too thick a layer at once the only cause of orange peel? what are other factors? Also, do temperature and humidity differences affect the color noticeably? I will be painting various parts of my car on different days, so i'm a little worried about this. Also, do the previous statements apply to the clear coat as well? Thanks again for your help!
btw..do you work in a paint shop or something?

Lets say i'm painting a fender once i lay down my first coat i will allow it "Flash Time" which is about 15-20min to settle before applying my next coat; then if another coat is needed I would then add another coat after the "Flash Time".If I were not able to apply all of the necessary paint & clear within 1 hour of each other, i would upon returning to finish; wet sand with 1000-1500 then apply another coat paint then proceed to clearcoat in the following hour after last coat of paint.
1st coat-15minutes Later- 2ndcoat-15minuteslater 3rd coat- 30min later - 1st clearcoat- 15min later- 2nd clearcoat ect.
Once You Start Paint Your Car or Part You Sould Apply All Of You Paint And Clear In One Cosecutive Time Period For Best Results
If painting in parts be sure to tape up previously painted parts to avoid overspay problems but it is recondmend to paint your whole car in one day
Orange Peel Is Caused By Underreduction or improper solvent/ reducer. -Paint drys to fast before it can flow out evenly. Also cause by improper air pressure usally to high to fix while painting basecoat/ clearcoat reduce more.
-do temperature and humidity differences affect the color noticeably temp does not really affect color but it affects drying times- if its hot you should use a slow drying reducer if cold use a fast drying reducer or pick a meduim reducer.
humidity i'm not sure about because i live in phx, az and it's usually very low
