im thinkin of havin a go at sprayin my new grill myself but i dont have a clue whats entailed and what i need to do it. do i simply buy a spray can and get to it? Is it even worth me havin a go or should ijust take it along to the garage and get it done there?
-
Easy enuff mate.
Get a spray can and give the new grill a very light rub with dry fine wet&dry paper first to give it a key. Hold can away from it and dont let can movement stop whilst spraying. Then top with some laquer.
-
I'm sure there's a flat & polish step in there somewhere? guess hardcore knows!
-
prep it like len said. use a a full can of undercoat sparying on very thin layers( leave each layer to dry fully) , sand again then do the same with paint , but sanding inbetween coats aswell, then lacquer in the same way but no sanding . also warm the paint up in warm water as it gives a finer spray.

Sorry! yes I forgot the primer and flatting down bits! :embarassed:
-
sounds ok to do, better than payin some mupped £80 quid to do it! :shocked:
So what exactly do i need to get out and buy? some wet and dry paper, a tin of black spray paint ect? and products to avoid or any to deffo get?

Although all of the above answers are close to the money, they're not quite right (no offence intended)
This is the correct way to spray a plastic part.. If your grill is brand new, the chances are that it will already have a primer coat already on it, sometimes the primer is the same colour as the plastic! check by looking at the front of the grill, then the reverse, the back should look shiney, this means that the back has no primer on it.. which is OK
If you've established that your grill IS primed, this is the next step...
DO NOT use wet/dry to rub down, this will remove the one single coat of primer in no time at all! Instead, gently rub the primed surface with a grey scotchbrite abrasive pad (Halfords) and some soapy water, your only lightly keying the surface so that the paint sticks to the primer!
Dry the grill, then degrease, and apply the basecoat (colour) in light thin coats, allow plenty of time to get the base on, its not a race! allow to dry for 10-15mins then apply the clearcoat, 4 coats should do it, allowing 2-3mins between coats, longer on a cold day!
If your grill came without primer, it is essential that you use the correct type of primer for that type of plastic!! (Halfords should know!) otherwise your paint WILL flake off!
what you need
Plastic primer (only if your grill isnt primed)
Grey scotchbrite abrasive pad
Degreaseing solution
1 aerosol of basecoat (colour)
1 aerosol of clearcoat
your colour code is located in the boot floor, on a paper sticker, it should read something like LN7Y
Plastic parts can be very difficult to paint! especially as manufactures are swithcing over to water based primers, that dont always take too kindly to haveing solvent based products applied over them :shocked:
hope this helps

Work in a paint shop do ya Tom? :wink: :laugh:
Most new plastic grills wont be primed and therefore the outside will be shinier than the back because of being in the mould.
-
hmmm, sounds complicated. Im sure its easy enough to do but i recon Il leave it to the experts.
-
I didnt do half of what he said and my grille turned out fine!
Basically Phil its worth havin a go just for your own satisfaction. If ya mess it up it can be rubbed down and no harm done.
Yes keep it clean but it aint worth buying degreaser for a little job like a grille.
Unless you cause a run in it I wouldnt even bother flatting down in between.

Len, how did you guess the bodyshop thing! :laugh: Ive been running my body & paint bussiness since 19!? :wink:
The reason that my post may have seemed a little OTT, was because a lot of people paint stuff like this, and it all goes tits up for them, usually ending in the paint pickleing up! so preperation IS everything
Anybody out there painted something for a second time.. and its 10 times worse than the first time! :cry: I know you people are out there.. because Ive had to fix them for you :laugh:
