Crackle Experience
Can someone tell me how to get a very tight (fine) crackle finish? My heater box cover has such a finish and I'd like to replicate it. Thank you.

Re: Crackle Experience
John,
Are you referring to a wrinkle finish?
If so, I understand an oven should be used.
Makes the wife crazy though...

Re: Crackle Experience
I believe there is a guide to doing crackle finish paintwork in the restoration tips section.
To get a fine wrinkile finish, I'd use two light coats of paint and then bake in the oven according to the paint mfs instructions........although as Rudy's already pointed out best wait until your wife is out of the house before using the Kitchen oven (lower oven in an Aga is fantastic for this!)

Re: Crackle Experience
Thanks guys. A few follow up questions:
What should be the temp in the oven?
Do I preheat the piece before each thin coat, then bake it again?
The piece is already epoxy primered. Would that get in the way?

Re: Crackle Experience
First, turn the oven heat to 200 to 225 degrees Fahrenheit. Let it get to that temperature. Spray the piece using two lights coats, turn the oven OFF and place the freshly painted piece
in the oven. After two hours or so, everything should be back to room temperature. I'd
let the piece sit overnight before handling. I recommend the oven be off since a gas pilot
light may be a concern with fumes from the paint. Send the wife on a shopping spree, you
both will be happy.

Hi John,
Primed pieces shouldn't affect the wrinkle paint.

Re: Crackle Experience
Heat lamps work well too if you don't want paint fumes in your oven. It doesn't take a lot of heat to get a good wrinkle. Experiment on some metal scraps to get the wrinkle you want. Worst case, paint stripper takes it off easily so you can try again.

Re: Crackle Experience
To avoid the wrath of the fairer sex, and since you live in a very mild climate, just use your barbeque outside. Since it's gas, just preheat the parts to about 200 F, then turn it off, take them out, paint them, then put the parts back in and close the lid if you can. I use VHT Wrinkle Finish. Here are the results.

Looks very nice. Add a few hickory wood chips for just the right aroma.

Re: Crackle Experience
Hi Guys,
Going back to my original point, I was specifically interested in experience with being able to produce some really tight wrinkle finish. The subject here is different from the cam cover finish. It is the finish that is seen on the back side of the interior mirror, the heater box, and often the racing 250GT SWB dashboards. The panels where the heater pull knobs are has this same finish also.
The finish is so tight that it looks like fabric stretched over the piece. Here's my heater box. Sorry, it's the best I have.

Re: Crackle Experience
That finish is not tight....it is extremely light in application.
Just like a bold line written in pencil is thicker than a fine line.

Re: Crackle Experience
John,
Rudy is right. In my experience a lighter / drier coat of paint will give a tighter finer texture. A heavier / wetter coat of paint will give you a courser rougher texture. It will take some experimenting to match your heater. I would start by trying one coat (on a scrap piece of metal) that has a course orange peel (when wet) on it. Make sure the coat is even or you will get a patchy texture. To get the texture normally seen I would use two to three wet coats of paint.
Cheers Jim

Re: Crackle Experience
Tried Rudy's technique. Horrible results.
Stripped the epoxy primer, then tried Rudy's technique... fantastic! It didn't like te thick underlying primer, I suppose.
Thanks a million Rudy!

Re: Crackle Experience
John,
Glad to hear that it worked out so well! I like the concept of primers
but have had issues in the past, so I just use the paint by itself now.
