Oliver,

if a shop has paint left over from a respray. can that paint be kept by the customer for future use such as touch up against rock chips? I figure that would be a better alternative to ordering enamal or lacquer based touch up paints offered over the counter.

I have however heard that urathane paints have bad shelf life after a week but I imagine that if it is in a sealed container it can be used for some time like house p aint

as long as just the colors and binder are the only thing that were mixed than you can keep it for a long time, if the reducer has been mixed than then it will coagulate in about a week

whats the difference between reducer and hardner? and why are these actually used in the painting process

reducer thins out the paint to make it easier to spray but it also helps the paint dry, hardner or catalyst actually makes the paint dry and harden

do you still use such addittives in your waterborne projects? I'd imagine there is no need with the benefits of waterborne and having an oven

waterborne paint dosnt need it but the clear that goes on it does

[bmwstephen]

hmm thats interesting why do most paint shops do not use waterborne clear. i do notice the base is an option

[oliver.r]

I'm not sure if there is waterborne clear?

Oliver,

after a car is gutted, windows out, and sanded down to the metal and is ready to be primed and seal. What is the process body shops use to clean off dirt and excess material from the body?

I can't imagine shops hosing down an entire metal chassis especially if customers have electronics, engine, and interior still in the car and possibly exposed.

[bmwstephen]

also why aren't you using chemical stripping on your m3 since you have the entire car gutted

we use a special cleaner and wipe the car down

i dont like chemical strippers, the smell terrible, hur your eyes, burn your skin, dont work well at all on multiple layers of paint, theyre a mess to clean up and if it gets on plastic at all it ruins it, i really dont like chemical strippers

can you go into detail? what are some brands and types? how do you apply them and is there a grace period you have to wait before you paint the car? or do you have to wipe it down with water after you apply the cleaners?

the cleaners are water based, im not sure of the products exact name but we use duponts sontara line of cleaning products ( everything we use is dupont)
spray it on, wipe it down, goes in the spray booth, gets hit with a tack cloth by the painter than its time to paint
