Crackle paint
 
2 Attachment(s)
I am trying to replicate the crackeled paint of an Avo 34 ranges.

There are few products to replicate that aspect, but the crackeling I got have very big lines and seems quite different.

You can see the original paint firstly and a test I did over a tin can.

Does anybody know how get a similar crackle paint as the original on the first photo?

Thanks

MGB dash repair paint is a crackle finish but I don't know how fine the crackle is.

Moderators, Excuse me, please move it to “cabinet refinish...” I open the thread at the wrong place

Thanks

Moderators: Thanks very much.

Ex seismic: Thanks! I will look for more information about that dash repair...

Those pictures do indeed look to show a crackle finish, often confused with wrinkle finish, which was used on a lot of electronic equipment, particularly American military equipment, and on vintage motor-car dashboards. Crackle and wrinkle are not the same thing.

I own an MGB which has a dashboard painted in wrinkly black. I could take a photo of my dashboard, if you can't find one to examine. If that is like what you are looking for, try Moss:

You might just notice that the Moss website calls it "crackle paint", despite the label on the can describing it as "wrinkle plus". Who is right?

Re: Crackle paint
 
My understanding is in wrinkle finish, the surface is continuous, but forms into miniature humps and, yes, wrinkles.
With crackle paint the surface separates into 'floating' islands with gaps in between, clearly shown in the second of the OP's photographs.
I'm confident the name 'wrinkle' on your can will be correct if it is intended for a dashboard.
I believe temperature is critical to getting a good even wrinkle finish.

I've used this on Avo cases and it looks like I would have expected the original to have looked when it was new and clean.

I cleaned off the old paint and started from bare aluminium.

The only difficulty is that the ambient temperature needs to be 22 deg. C to get the right effect and that's a rare temperature here, some summers it never gets that hot. Possibly not a problem for Aitor.

Another test...

What is your opinion?

Little bit better I think

Thanks to everybody!!

I will try to order that paint. Not sure if they can sell it to Canary Islands

Frost's refer to their paint as 'wrinkle, crinkle or crackle'! We can't win!

Hi,
We use Crackle or wrinkle to repaint the heaters in classic Mini's. I think it comes from Frost and from memory says 'wrinkle' on the aerosol.

It's extremely difficult to get it to wrinkle nicely but it is possible. The application technique is critical and you will need to do lots of experimentation to get it to work correctly.

The heaviness of the coats, the time between coats and the temperature are all critical. Sometimes we need to heat it gently with a hot air gun if it won't wrinkle! The wrinkle seems to be generated by a reaction between the first and second coats.

Your first picture shows exactly one of the many problems we have had. So you probably already have the correct paint but need to experiment with the application and temperature.

Hope that might help,

Good luck
Nick

Apparently Powder Coating companies can do a very good wrinkle finish. Much more expensive than aerosols I suspect.

Hi

When I were a lad... my dad sprayed our Practical Electronics Oscilloscope in crackle paint. It wasn't anything like the pics. Imagine an enourmous flat tray of cornflakes viewed from a long way off. There were no discernable patterns, the paint surface looked almost sharp. Like a tray of sharp sand perhaps.

I quite liked the 'hammer' paint too - not mentioned so far - this looked like a really hard enamelled surface that had randomly been hit with a hammer making what could have looked like pools in wet paint.

I have an old RAF R1082 radio which looks like the crackle paint as I remember!

Re: Crackle paint
 
The MG Owners Club spares business sells two variations on dash wrinkle paint. Prices quoted in pounds, euros and US dollars so they obviously ship world wide.

Camera Crackle Black was what the paint used to be called.Somewhere I still have a can.

I am a member of the MGOC and have just visited their website. I could only find one paint which was described as "dashboard wrinkle effect paint", but it was listed under about three headings. It is listed as A029.

The MGOC Accessories Catalogue also lists A029 as "VHT Wrinkle Plus" and shows a picture. It describes it as "suitable for rocker-box covers and dashboards" and states that it is heat-resistant to 350 degrees F.

I used to have a can of paint for touching-up scratches on my MGB dashboard, but I can't find it now.

I have taken a photo of my MGB's dashboard with a steel rule for comparison.

Regards, Colin.

I have used red VHT Wrinkle to refinish a Lotus cam cover. As previous posts have said it is temperature dependent. I pre-warmed the cover and after spraying suspended an infra red reflector bulb over it until the paint had cured and wrinkled. The result was a perfect uniform wrinkle finish.

VHT "Wrinkle Plus"
I buy mine from any "hotrod" car shop. Its available in about 10 colours.
I havent found it temperature dependant, but I do live in a warm climate.
I wonder if any of you have read the directions on the can?.

Reading the label on the can.

1. Clean the surface to be painted.
2. Spray a heavy base coat.
3. Apply two or three lighter coats about 2 minutes apart. Size of wrinkles is determined by the number of coats. The more coats the bigger the wrinkle pattern.

I have never had trouble making the paint wrinkle!!

Just my two bob's worth.

Joe

PS. I should have added, just to add to the confusion of the name, In days long past it was called "Brocade", and most of Australia's older transformers were painted with it.
