Anyone know the difference. The man doing my current bodywork changes has texted me asking if the car has ever been sprayed anywhere else other than by him. I texted back saying I don't believe so (while I've owned it) and he texted back saying the paint finish underneath is cellulose based, which is why his original respray last Autumn may have gone off like it did.

What's the real difference? Is it likely my car was involved in an accident prior to me taking possession in Feb 2004, and has been "botch" repaired. This could also explain when a rear arch started bobbling and needed repairing - the same chap repairing it said it had been basically "filled" and painted over.

I don't think if the car has been damaged, it went through insurance as the quality of work is obviously pretty sub standard.... However, it doesn't take anything away from the car and it works fine / handles fine (Well, I have pretty much replaced everything at the front end)

So, what's the difference with the paints?

Not familiar with the term "Y2K" wrt paint, but if you can tell us more about that paint, I might be able to help.

You'd be suprised at the number of brand new (unregistered) vehicles that get damaged and have paintwork even before they are sold, so I wouldn't worry to much about it.

Cellulose paints replaced the '2 pack' paints that contained cyanide, not sure what a y2k paint would be though.

Em, doesn't cellulose paint pre-date 2-pack cyano-acrylic, by a hundred years or so?

Maybe it was that way round, cant remember now I think about it!

Is paint today water based and if so will it mix with cellulose paint????

Technically all acrylics are water-based.

What do you mean by "mix"? You can't spray a mixture of cellulose and acrylic in a single container. You can sometimes put one over the other without them reacting, but I've seen them react by crazing (like the mud at the bottom when a puddle dries right out) or bubbling, when one is sprayed over the other, or brushed cellulose lift and melt acrylics.

Ken.... I was meaning can you spray one coat of one and then spray the other on top??

Not recommended as a rule.

I got it a little wrong. He just said it wasn't "2k" paint. (If this helps)

I can't be certain, and still don't recognise the term, but what he's saying is plausible.

So, I guess it probably implies he's done a little more work getting the bumper back down to a surface he can reliably paint, which will last a long time yeah? I've got him to check my rear right arch again, as on my last carwash (yes, it was fairly recently... ) I spotted a sliver of corrosion starting right on the corner. :(

2K i think referes to the fact that the paint is sprayed in 2 parts , the colour coat is applied first then the clear lacquer coat over the top , its also called 2 pack iirc

cellulose paint was sprayed and built up in a number of applications to give a shine

In which case "2K" paint is more normally known as "2 pack" IME, and is (usually cyano-)acrylic.
