How do these things work? I know they take a layer of paint off the top and all that but how do they do that? I don't mean scientifically though.

 

Isn't there a lacquer on top of the paint? If so how do these products manage to get to the paint?

 

Also, people use rubbing compound to mix in old and new paint right? So how does that work?

 

Any help would be great as I've been doing a bit of spraying (headlight panel) and feel that a bit of knowledge might help me become one with my spray cans ;)

 

Al

T Cut is a mild abrasive.It removes gunge and swirl marks on paint or lacquer.Gives a nice, as new finish to apply your polish too.

Can these products have any effect on the actual paint though if the paint has a clear coat on top of it?

 

Thanks for not shouting at me :)

"NO"Lol :)

Metalic paint has a clear lacquer on top which can yellow over time.

T-Cut Metalic rubs a micro fine layer of it away back down to good clear lacquer so your paint is returned to the original colour.

 

Standard T-Cut is for regular paint colours that don't have a clear coat so it's the paint itself thats rubbed away making it look like new.

Thanks ;)

 

I didn't think so. Just finished my headlight panels and have done the laquer but now have to wait a while before I can use the rubbing compound.

Aah! That explains a lot. The bonnet of my car has patchy areas where the paint seems to have lightened. I've used t-cut on this and some other similar product and they have had absolutely no effect.

Mines red and it has a clear coat. :cool:

What colour is your car?

 

The classic use for T-Cut is when you see red cars with bodywork thats faded to pink or a white haze over it.

It comes up like new.

 

Metallic cars tend to just lose their shine or in the case of silver it dulls and goes a bronzey shade.

Worked wonders on my silver Z when I first got it.

Why? Just for bling??? LOL :rofl:

Never heard of that before.

Are red zeds not metallic then? I thought metallic just meant the paint had little specs of metal in it, why does it have to be metallic to get a clear coat? Surely the clear coat is a good protection for all paints.

Nissan AG2 Red is a two pack,ie base colour and then lacquer top coat. :tongue: :)

I'm no paint expert but 2 pack paint isn't 2 coats...

I'm not saying yours doesn't have a clear coat but sounds odd to me.

The standard red definatly has a clear top coat (as I've seen the laqeur peel away on a couple of them).....but I dont know enough about paint types to explain why...

Metallic is to give the paint sparkle but it doesn't give a very smooth finish on it's own so a top clear coat is there to enhance and seal it I think.

 

Red is usually red!

Most metallic reds tend to be burgundy type colours or candy apple stuff.

Most factory finished cars these days have a clear coat regardless of the colour. The base coat is applied whether it is a solid colour or a metallic which on its own has a semi matt appearance and then a 2 pack lacquer is applied which brings the final colour out. You can also get 2 pack solid colours which give a more durable finish than single pack paints, 2 pack being that it consists of a colour or clear coat and an activator which starts a chemical reaction to harden the paint when the two are mixed together. The clear lacquer creates a deeper and more attractive finish which is why it is the preferred method.

AG2 red does indeed have a clear coat from Nissan. Mine is peeling in places.

Reds are notorious for fading/oxidising and I guess this was Nissans attempt to help cure the problem?

Common misconception. 2 Pack is not 2 coats as has been mentioned earlier - PPG do 2 pack paints - you only apply one coat of colour paint - The formulation of the paint is the 2 pack part.

 

A colour coat and then a lacquer coat is just 2 different applications one after the other.

 

I'll get my coat.

I'll get my coat.

 

Is that your top coat or base coat? :rofl:

What he said :cool:

 

It helps prevent faded paint etc. If you T-cut an old car (say 1984 or earlier) you will notice some colour residue on the polishing rag, as the T-cut removes the top oxidized layer of paint.

 

However T-cut a car from the late 1980s onward and there will be no such residue. The polish simply renovats the top layer of "clear laquer"

Ok

I worked for ICI Auto Colour, PPG (now the same company) and also

Max Maya. 2 pack is a generic term for a paint that has 2 parts to it

ie: Paint and activator, These are mixed together in the correct ammounts

like resin and hardener.

Two pack paint can be solid colour that is applied with out a second prodoct

over the top teh colour goes right down to the primer.

The second is base coat and lacquer both these products are product and activator,

but the basecoat gives the colour and the clearcoat gives the shine.

 

Solid colours fade with UV, red the most!

With the clear coat the fade is less as the product has UV sceening

so fade is less as the base coat dose not get effected!

 

Single pack paints do not have activators, these are mainly

Cellose or Tractol type paints and the automotive world

no longer implaments this type of paint anymore.

Most new automotive paints are now aqua base and no longer

2k products ie spirit/resin

The reason your car is baked in a low bake oven is to cure the mixed

paint and activator, and give a durable finish also it speeds the hardening prosess up

 

 

Hope this helps a bit

 

If your car has clear coat you should not use a cutting compound that

contains AMONIA, as this yellows the clear coat.

 

T CUT ORIGANAL has AMONIA in its chemical make up, and WILL yellow your

clearcoat.

 

There is now products for clearcoat cutting, use them!! Safe cut is the most

common.

is it possible for the colour to fade whilst underneath the clear coat? if so how would you fix it?

Only in extreem sunlight (not in the UK)

What you need is to have your car machined

to cut the clearcoat, it would bee £80 to £100

well spent
