Why is this proving to be so bloody difficult,if it had been solvent 2k paint i would have been finished days ago!All im trying to do is fill in a stone chip on my motorcycle tank,that's it!
Using this water based crap to do it as that is the only paint the company supplied,and they're the only company that supplies the colour.spot of solvent primer,flattened,then touch in with this water based muck,heat build up in my garage all through this.Waited a whole day,touch of 2k lacquer on top of the chip jobs a goodun,eh nope,basecoat disappeared when lacquer touched it?Brilliant.
Right i thought,put basecoat on the chip in thinner layers,add more heat,wait '2' days this time for basecoat to dry then try again,nope, basecoat disolves again.
So i've repeated this process several times increasing to three,four days for the basecoat to dry,still no joy!
Do i have enough of my life left to repair this stone chip?

It"s only this one company that supplies the particular colour of paint for this bike(kawasaki,use them exclusively)so it"s not just a case of asking for a chip repair kit somewhere.I'll check chipex though to see if they can match it.

The colour is eventide purple off a 1993 kawasaki Zxr750 motorcycle. Code on the bottle of water based garbage I received is Kawasaki 2763,a number which meant nothing to my local vehicle paint supplier incidentally.

Had a look at the system I use - Aquabase Plus.

No listing for that code or colour name.

Searching for Kawasaki colours for 1993 gives various colours but no code or colour name matching your code or colour name although Kawasaki colour codes are singularly lacking.

Possibly a colour that they never formulated or is obsolete & has been deleted.

Much the same result looking through the oldest DuPont book I've got which is from 2005.

Where did you get the code from?

I've used waterbase for some years & never had a problem using 2k clear mixed at the clear maker's recommended 2:1 plus 10% thinner.
Are you using too much thinner to try & get the clear to flow out more easily & reduce build?

I wouldn't be at all surprised if a 1k clear caused the dissolving - much the same happened if spraying too wet a coat over solvent basecoats!

What have the supplier of the colour said when you contacted them about the problem?

What he said /\

Most modern vehicle manufacturers now use w/b paint and 2k clear .........!

Also w/b won't take days to dry!
Try putting a drip of water close to your work area, and when that's evaporated (which won't take days) you can rest assured the paint's dry.
Although it's called waterbased paint there's less water in it than .......... water wink it just hasn't got the high voc (solvents) in it.

The code was just what it had on the label of the bottle of paint the company sent me. As for thinning etc it also says on the label 'ready to use' so I'm taking that to mean nothing needs adding?
I didn't contact the supplier about my problem, just called my local painter. All he said was paint I applied on my paint chip would have been thicker than what is sprayed normally out of a gun, which was understandable, and to just leave it a lot longer to dry!

Speak to the supplier of the paint. They are more likely to know than a 'local painter' - or may have met the problem before.
The code on their bottle may be their own code. Have a word with a Kawasaki franchised dealer to see if they can help.

Use a hot air gun - or a hairdryer on its hottest setting - to move hot air over the chip to assist with drying.
Don't get things too hot or you'll damage the rest of the paint!
As Squiggs says, a drop of water next to the chip & when that's all gone then the paint should be dry as well.

Decided to have a look at it today whilst doing a customer's car.

Couple of drops of waterbase onto a tin lid.

Hot air gunned for around 5 mins.

Big drop of 2k clear (mixed as in my previous post 2:1 plus 10%) plonked on top of the colour coat.

No reaction of any type.

I repeated with a lot more thinners in the clear (20%) & it did affect the base so I wonder if that's the problem you have.

Makes sense really ........ it's possible to clean a w/b gun with thinners - so logic dictates thinners has an adverse reaction to w/b paint.
