new painted body panels

[fil_b]

hi all

how long would you leave a new body panel before waxing?

month or so?

tar

feebs

Doesn't matter, some people say you should let it get outside for a week and get the paint used to the elements and stuff but bare in mind these panels are machine polished before they are given back to the customer.

It'll be fine.

I keep hearing more and more stories about bodyshops it's not good, I work in a very good bodyshop who take a bit of pride.

What I can say is because things are getting more expensive and you get less time for doing jobs the work suffers as it's being rushed out the door.

I think it's happening a lot these days.

it depends, if the paint was flashed off (cured) properly in an oven then it is fully hard within an hour of coming out the booth so you can wax straight away.

If the paint has been left to air dry then it can take up to 8 weeks to reach its full hardness. By waxing the car you stop the water in the paint evaporating so it will stop the paint setting as quickly and to its full hardness.

Air dried paint are never as hard as baked paints

Surely people can't be air drying cars these days Rich?

there are still a lot of garages and "bodyshops" I have spoken to that do. The paints used in each process are different. When they are baked on are completely water based (lacquer is still solvent based). When they aren't baked on there is an additive to allow the water to evaporate in the atmosphere on its own, which is part of the reason its softer, these paints are the sort of things you'd buy from Halfords in a spray tin.

Baked on paint require very little to no polishing afterwards. Air dried paints require more

not sure what process they used

i know they didnt take my door off when they did that

got over spray on my rear quarter they got to sort also - as well as bits under the paint

Oh dear I can't see it getting any better tbh. Good luck tho.

Rich, polishing is really just de-nibbing little specs of dirt ect... from the paint.

IIRC solvent paint is illegal in bodyshops now.

It's cellulose paint.

most places spray in a booth, but dont have the ability to flash the paint afterwards.

Its normal to respray a door while its on the car, it allows you to get a far better colour match to the surrounding panels and blow into them if you need to.

Most good bodyshops will always run the buffer over the paint when its done, but if the sprayer is really good it will need very little finishing afterwards.

All base colours now are water based, but Lacquer isn't there isn't one out thats as hard, and as sparkly as the ones they currently use. When I say solvent based I dont mean like the ones they used years ago

Yeah I was getting confused, paint isn't my strong point bodywork mainly is.

I would say unless your booths are very expensive the sprayer can be the best but there is always particles in the air, that's what de-nibbing and polishing is for.

very true

tbh I'm not a sprayer, or anything like that. My company sells spray booths for the automotive & avaiation industry so I've picked up sooo much knowledge about it since working here. Its been very handy when it came to getting some work done on the 182

Invaluable stuff to know mate, painting cars is expensive and not something you get 2 shots at so it's good if you know what you're talking about.

What company do you work for mate?

I know, its been a real eye opener working here from that point of view.

There are 3 companies in the group and I'm always between sites. The company that sells the booths is Dalby Engineering
