Default A source for wrinkle paint

I've just read an entry elsewhere on this forum, contributed by Mike Phelan. He suggests a site where chassis paint might be found. I took a look and found they also stock wrinkle finish paint. As this was the subject of previous enquiries when the only source seemed to be Antique Electronics Supply in the USA, I thought those interested might find this worth bookmarking:

http://www.frost.co.uk/item_Detail.asp?productID=8219

The paint is aerosol and is available in black, red and grey and should prove ideal for the restoration of items such as comms receivers, valve tester panels as well as other gear such as movie projectors.

Hi Tony when we looked into this before it was thought to have too big a "wrinkle" as it is made for car dashboards. The good old fashioned way of obtaining a wrinkle finish is to spray a cellulose top coat over an oil based undercoat but I must admit I've not personally tried it for about 35 years

Hi,
I have tried the car aerosols and have found that they don't work particuarly well. I have not tried the cellulose over oil method but must give it a go.

What I would like to try is to use proper stove enamel wrinkle paint. Although I have had this done for me by professional paiters I failed to track down a suppleir of the paint so I can buy from them and have a play.

Does anyone know a supplier?

Robin

Hi.Now I've heard/read somewhere that this type of paint as suggested (car dash' etc) can work better if the "?" it's used on is heated first ??,ie in the Oven (Don't let the Wife/Partner hear about it) !!.I've NEVER tryed this out but assume the paint hittting the warm/hot surface shrinks ? thus narrowing the crackle effect.Imagine a LOT of experimenting would be needed first !!.John G1WOS.

Hmm. When I used an aerosol obtained expensively from the USA, the effect was highly temperature dependent. The density of the sprayed coating - heavy or light - makes a big difference to the strength of the wrinkle pattern. Warming the object to be sprayed varied the effect, also it is possible to use a hair dryer to speed the process and this too has an effect on the size of the wrinkle. With practice you can vary the wrinkle size at will.
I thought the cellulose over oil was a crackle effect, not a wrinkle, but I'm probably wrong there. If you want a good crackle, use emulsion paint as a ground coat, or water-based paint

p.s. Perhaps this topic should have been entered under a new forum listing called 'Radio Wrinkles'
-Sorry

Hello .
I've tryed a spraybox of wrinckle paint....results were not really good.
I think you need to have experience first ,before you try it on
you loved item.
My advice:If you know a experienced painter with this wrinkle-paint,go there
innstead of try it yourselve.
Succes!!

Hi,

What is the difference between crackle and wrinkle? I've always referred it the finish as crackle, probably in error.

Regards

John

Hi John
That does seem to be a common misnomer. Wrinkle is paint that has increased its surface area as it dries - so it is, er, wrinkly. Like an AR88 case or some car dashboards like MGBs or my DS.

Crackle is paint that has shrunk as it dries, so you get a myriad of sunken lines on the paint - a bit like very fine crazy paving!

Both difficult to describe! Have a look at Frost's catalogue.

You are welcome, John - I think it is almost one of those sort of 'urban myth misnomers'.
