Flatting, Cutting and Polishing 2K Paint

Any tips??

I've got the sunroof panel in the house now and its been hardening off for a few days, so i gave it a wee flat with some 1200 grit paper - worked a treat, nice n smooth.

Got G3 compound aswell, so tried it by hand, followed the instructions, damp cloth, apply to surface, spray with water occassionally - but can i get it to shine - can i fuck

It just wont get rid of swirl marks or faint lines

Its been in the house since it was sprayed on saturday evening - so should be fully hard by now eh?

I am gettin 1500 tomorrow and can get 2000 if i want, would usin those papers make the whole process a lot easier?

Its metallic black aswell, so prob the worst feckin colour

 

Andy - need to polish it after the G compund proces to bring out the shine....

Had to do the same ot mine. The G makes it a dull shine, then the polish will bring the shine out..

 

youl need a machine...it'l never shine by hand(it would on small bits)

i only use 1200 on nasty orange peel or big bits of poo, then go over it with 1500 then 2000 if your fussy

i use g3 or 3m fast cut which is more aggresive

pm me if you get stuck...i do that job all day

 

Yeah tried a bit of autoglym on after i had done a bit of polishing, full of wee marks - so did a bit more, still the same

I was only doin a wee area to see, so it shouldnt take 5mins per 3" sqaure should it??

Ah fuck this is gonna be some job i fear

 

Ok, looks like i'll get a machine....

Seen some cheapo types on ebay, 3 year warranty for 50 cant be that bad surely.....

Have a look here and see what ya think


Would that do the job??

May aswell buy one as opposed to hire one, if i even can up here....

 

It WILL SHINE BY HAND, but just takes ages to do it and you end up with no skin lieft on your fingers !!
But is easier with a mop and a darn sight quicker..

If your gonna use a mop, make sure you don't burn the paint with it, or go through it as well.

Screwfix sell the sponges and G3 compund just in case you need anymore.

Small scrtahes can be taken out by Macquires stuff, do they look like swirl marks ?

 

I can get the mops and G3 and G10 compounds at the motor factors up here

Gonna need a mop - cannot be arsed with weeks of hand polishing, gotta rebuild the bloody thing aswell mind

 

LOL - ahhhh this brings back fond memories of using the parents garage for the fortnight when they wen toff to tenerife. Turn it into a paint booth, sparyed it, then compounded it and polished it all by hand, put it back together, and then relalised the whole garage was f*cking red - the parents relaiased what ad happened !!

If you can see swirl marks in the paint under flourescnt lighting then its normally scrathes left from the compounding process. These can be cut out before polishing.

 

Hopefully the 1500 will make it a lot easier - will get some tomorrow and give this hand malarky a try, see how it goes.

 

MAke sure you use the 1500 grit with a soap bar and water. The soap will stop the paper from clogging, and less scratching Andy. Happy rubbing !!!

(I don't envy you at the moment )

 

I always use soapy water, fairly liquid, as i have a bood that said it was best cos it makes the water cling to the surface.....

Jus prayin that the lacquer goen on pretty good tomorrow, or i'll be making a hell of a lot o work for myself de-orange peeling the whole car

 

I havent read all this so sorry if its already been said but use G10 after the
G3 to get rid of the swirl marks

 

ummmm..... that's the problem I had. Cold weather, spray paint, one heater, recipe for orange peel !!!!

Good suggestion bout the G10 by the way.....

 

Well the farecla site doesnt speficially say to use G10 after G3, so

Certainly keep that in mind though to give it a try.

 

Andy You need to used 80's on a D'A make sure u get right in there with it that will get rid of your damaged paintwork once finished with the 80's use an angle grinder that should give a really smooth finish.

You'll know your done as there are no swirls left in the panel

 

g3 liquid on a mop will leave a good enough finish...any good wax over the top will sort out any haze

 

Got some 1500 and 2000 grit paper today from the bodyshop guy, he even said i could get a loan of a polisher if there is a day they aint using it.

 

anything else you need im gona be painting soon too

 

Heaters, parafin/propane space heaters - you need to get the place warm.

 

aint got any of them but im gona be doin it satin black
