On Ven Red BXs (or most red cars for that matter) is it UV related or oxidation? Just wondering if a clear laquer would cure all?

[docchevron132]

clear wont do fuck all mate.
I mean, it'll take longer, but yeah, it'll still go pink. I know this, the OSR wing on the diesel is clear lacquered, and it's the most pink panel on the car. It also the oldest (original) panel on the car.

It's UV mate, not much you can do about it really.

Just thought......why don't me painted bumpers fade? And, it seems to worse on the bumper and scuttle than say the roof, even though they is all the same relative tot he sun...

I have the cure. And so does Vanny, unless he's used it all.

I've posted before about it, it's one I used to sell at 8 quid a throw, it being a polymer sealant.
It will lift off the oxidisation, bringing back the colour and sealing it against further attacks if used about 3 times a year.
Take a look at mine in the garage. It was taken just before I posted it there.
Unfortunately I am down to my last bottle.
It takes out minor scratches too.

the paint used on the bumpers and general plastic bits is not the same as the metal bits though is it?
Certainly the original bumpers on mine were prepped differently to the roof / other steel panels?

[Philhod]

The earlier, ie, not dead smooth ones were polyprop were weldable and used a plastic type paint, where they were indeed painted.
The later ones be of a smooth polymer that has a special black base that then takes normal paint and don't weld too well at all.

My immediate response to this question was "Because it tastes nicer than brown", but now I see what you're on about.

But I think the reason red paint fades faster is that the pigment often used more easily forms a (pink) oxide than other pigments, with the action of UV light.

[Philhod]

My immedeate response to the last post was, that he must have tried both, to have a preference

The reason for pinkness or any dulling is due to the amount of pigment required to produce the shade. That's why reds and worse going into brown (sorry) such as maroon are the worst affected, followed by darker blues. White of course is the least affected but tends to absorb shite.

Well, if it's a pink oxide then a clear coat would prevent this!!!!

I polished some of me panels and they have stayed mostly red

Any good polish will bring the colour back Bandit, but only a polymer sealent will stop it returning.

[Vanny]

stop the colour returning? Your mad!

Red pigments are never very stable in UVa (think its UVa that kills pigment), it's not just paint either, red is just generally a fecker of a colour. But i don't mind pink, which is fortunate!

[Philhod]

If you can't spell it your a dunce Know what yer mean

Have you used all that bottle I gave you Vanny, cos I can't get any more

[Bx Bandit]

So this polymer sealent does what? Presumably it 'seals' the paint from the air?

[docchevron132]

fuck knows, cant see how it keeps UV out?

[Bx Bandit]

it prob doesn't mate, fuck knows. If a sealnt works then it can't be Uv I'd of thought. Not to trash Phils input at all, I'm just an intruiged red wannabe!

[Philhod]

The polymer sealant adds a layer of a very fine polymer chain, over the surface of the paint.
I think the bumf said 6 microns thick. This protects the paint from both U/V and atmospheric oxydisation.
The first ones came out in about 1970 and were added after polish and not mixed in with it, as mine is.
I remember an advert for one of them actually lit a fire on the bonnet to show that even heat would not damage the paint. but I never tried it myself
As I said before mine has had it applied 3 times a year since I got it and there is not a hint of pink. Pics in garage.

hmmm, this stuff you have Phil, I seemto remember it was rather good, is it still available?

[mnde]

Why don't you rub SPF 50 suncream into the paintwork. SORTED

Mark.

[docchevron132]

fuckin' genius!

Piz Buin!!!
