Anyone know how bodyshop re-spray work differs from the original paint process by the manufacturer?

For instance, I understand modern paint is actually matt - it's just the lacquer which gives it the gloss. Would an MB approved bodyshop also use this system? Apologies in advance for disgraceful lack of automotive knowledge.

Body shops by law have to use the latest water based paints that are a base and top coat lacquer, there is no other way

well most large body shops now only use water based. its a long drawn out process per coat that i believe takes a day per coat to cure so each re-paint or panel can take upto 3-5 days where as 2k can be done in a day after preperation with the paint cured enough to be subject to the elements the following day on air dry. many cars i have painted have been driven the following day some the same day.

Not so now,, the modern guns dry the paint as it comes out of the gun, and the oven finishes it of in 20 mins, Job then done, in fact very fast

Malcolm I have to disagree somewhat .. modern day water bases do take much longer to dry than their solvent based forerunners.. this entails blowing lots of warm air (not hot) over the painted panels..some bodyshops even bake the waterbase for ten mins before applying the lacquer.. actually a good windy day outside around 12degrees is the best way of drying waterbased paints...and believe me they are slow .. painting time on a panel is possibly doubled from the solvent based process..

Modern water based paints are almost impossible to use without an oven, and they are in the oven for around 20 mins, when they come out they are ready for the road and finished,, I spend a lot of time and do work for my local one

Without an oven the cars would pick up dust and rubbish

Yes but you will find that the oven has had extra blowers fitted to dry the water base the outside scenario was just an example

Fair enough :wink: the oven that we use down here is a few years old and it does not have any fans to move the air, the modern guns do this to a great extent

These guns interest me malcolm any chance you could find the make or model.....some of the newer equipment gets field trialled before it hits the market

Yes the manufacturers have the technology and the bodyshops are basically left to make do..even talking to other bodyshops they all love waterbase paints..but talking to the painters and things are much more in dissaray..they basically dont like waterbase..

Hello extractorfan again,, I was a little bit wrong last night, so sorry about that.:(

The new guns atomize the paint so fine that it dries very quickly, thus giving a shorter time in the oven.

Some are getting used to water based paint, the only good thing is that with the older paints even with breathing gear the painter stood an 80% chance for getting Asama

I Just Don't Understand.

Gents

With all due respect to your great knowledge, and acknowledging that the problem may well be the few drinks i have had while reading your posts, I must reluctantly say that after having read your posts a number of times I am still unable to understand whethere or not you are saying "yes" there is s a difference between the factory paint job and the paint shop or no there is no difference.
WOuld you please clarify the position.

Thank you

With cars say from 1999 to 04-04 the paint process would be the same as was on the car from new, after 04-04 the paint changed to Nano paint, this is a ceramic paint thats fired on when the shell was made,,it is not possible to repair Nano paint owing to the very high firing temperature used when new, and any repairs here would be done with normal water based repair techniques

Basically no, the factory paint was always much more techncally advanced..due to the need and the higher number of cars a manufacturer would be painting...The aftermarket painting process used different paint ..albeit made by the same paint companies..but in general its almost as good as the real thing... some of the smaller car companies like lotus and possibly aston martin tend to use very similar painting techniques to todays bodyshops... for instance i do know that ford and vauxhall were using a paint called TPA in the 70s onward ..and TPA basically stand for ..Thermo plastic Acrylic ..but as malcolm says things have now moved on even further...
