polishing after respray

stirlinggaz · World Chat Champion Joined: 22 Jul 2007 Karma :

hi all,
almost finished respraying panels,
& its going ok.
just the last couple of coats of clearcoat to do.
what product would be best for polishing it up afterwards?
heard horror stories about t-cut,
so what would proffessional spraypainters use & when?
any advice gratefully received
cheers,
GAZ

Depends what your polishing for
Do you have dirt/nibs in your paint?

thats the only reason you would do it, but thats a bit silly asking that now as youve already sprayed your clear so any in the basecoat is now locked in..

Hi,
nope, no dirt or anything.
looks ok (so far)
just got the last load of clearcoat to go on, but ran out of 2k thinners!
i only need about 50-100ml!
reason i was asking about polishing,
i was under the impression that i would be better giving it a good polish then glaze (presuming to "seal" it?)?
is this wrong, should i just wax it?
cheers,
GAZ

Theres :
Polishing
Compounding

Polishing is giving it shine
by using something like Farecla Total or similar

Compounding is when you have oxidised car/dirt/trash in paint
for this ud use Farecla G3

If your just trying to achieve the shine, get some decent car polish like the farecla polish or whatever and put it on using a microfibre cloth, they only cost a couple of quid for the cloth and buffs alot better on sensitive fresh paint that using a machine buffer will.

On the other hand, if youve done a good job
and theres no trash on it then you just need to gloss it with the polish, or you could leave without as the topcoat/laquer is a seal.

Are you talking about getting the CC shiny after blocking it to remove orangepeel?

If you're talking about wax etc don't bother for at least 6-8 weeks. You don't want anything sealing the surface for a while...

Paint takes like around 8 weeks to properly harden, thats when you should start sealing with wax

You should have a nice shiney job, if youve applied the clear and base properly in the right coat consistancy.

Thats what laquer/topcoat does seal the paint in and add a gloss coating to protect it,

It is easy to get impatiant and polish too soon, Leave it a couple of weeks.

You can put them back on,
but the smallest of knocks/taps
will probably ruin your paint as you havnt baked it,
=/
which could be a bummer.

Whack it in your airing cupboard, or a place that gets nice and warm around 30 degrees,
i usually stick it under the heater in my room and wait for the heating to come on Laughing

or just be extremely careful putting it on, and dont torque bolts tight as it will just rip the paint off.

Err darn,
sure you mixed to the right ratio?
and dont worry its a common thing to happen,
just knock the runs off and try another coat.

And if it isnt your house make sure your parents dont go mental at using the heating in this weather Laughing

Id i were you id go slap the bloke in the shop about mixing till it feels right.

The ratios on the paint is for a reason as the manafacturer recommends that and has tested it at that to find its the optimum coverage, viscosity and such.

And i have to warn you before you get flamed, wearing anything but air fed respirator with 2K can be fatal. We had a bloke come in who was painting for 15 years with cellulose, first time he was using 2K got it on his hands, and was wearing a skimpy mask like your using. He has a illergic reaction and had to quit the trade, when ever he goes near paint (with isocyanates like 2K's) he breaks out in rash's and stuff.

and Isocyanate is odourless, and colourless.

Heres a link to a pdf document from a government website about using 2K products.

hi,
im using a respirator type mask,
it has a plug in filter which says on instructions is ok for short periods of use with isocyanates.
eyes & skin are covered.
literlally only in contact wit vapour for 2/3 minutes as i only have space to do 1 panel at a time!
prepared to risk it.
im nearly 40 & have abused my body with far wose chemicals than this. lol.
cheers,

The mask lies
there is no substitute for air fed masks running at positive pressure.

Trust me you dont know how lethal isocyanide is.
If i remember cyanide on its own is a form of poisen.
I heard about a bloke who resprayed his car using a mask like yours (not air fed) and was extremely ill for the next 5 weeks running. so unless you want to spend some time in hospital, id tread very carefully about doing this kind of tihng in future.

You can use mask/cartridge filters.. but they had better be the correct type.. & those charcoal ones ain't them..

& as for the advice about thinners...
No one has mentioned if it's slow, mid or fast thinners?

tutton · World Chat Champion Joined: 04 Jan 2008 Karma :

Want to link me to somewhere i can buy one of these masks with the correct cartridge.

I asked a bloke selling the 2k paint cartidges on ebay and he said there was no substitute for air fed masks unfortuntatly.
