the grind look?

[Duleyman1]

Im getting ready to do a new technique to me, its where you put grind marks into the metal on a tank and fender and then Kandy Koat over it and it gives it a neat 3D prizm look.
I am ordering a tape out of airbrush mag. that shows how to do this, but I and hoping someone out there has done this and can give me some insight into possible problems before they arise. I paint professionally in Indiana "I own a paint shop" and Im concerned about the delam of clear over bare metal. Any imput would be greatly appreciated.
Thank you
Bruce

I did a 3'x4' aluminum sign with apple red candy over grinded flame shapes back in July with no prblems of adhesion.
It currently has been hung outside since then with no problems to date. Its in direct sunlight all day, rain and of course our famous -10 below snowy days here in Minnesota. Personally I'm surprised it's still there.
But for safety sake use an adhesion promoter over the bare metal.
Good luck,
Dirt

I feel the same way about the delams.I heard HOK's adhesion promoter and a very,very light coat of etch primer works but i'd have to go the HOK route.Scary,but I'd do it with no guarrantee on peeling.Very cool effect but it's faded out in the last few years.

i was at the Frank Marada auto show over the weekend and talked to a couple guys from PPG. the product your looking for is Spray bond adhesve and you have to get it from a sign supply store or at least thats what i am told. grind up your metal, spray on the spray bond, then clear, let dry scuff it up and then candy away. /ubbthreads/images/graemlins/luck.gif

I think the HOG adhereto is the same thing as the PPG spray bond adhesive.

 

[seedeucer]

Typo. Should have been HOK.

But how do you get that grond look, witha DA, what grit if so.

I have a small air grinder that I use for this effect that uses the little 3" grinding wheel. Just get after the metal and grind swirling patterns or whatever floats your boat, you'll get the idea once you start. I use Bulldog adhesion promoter, it will make paint stick to anything.

I've done the engine turned look then candied over it. Looks a lot like anodized engine turned aluminum. Hog Adherto... think I shot a low rider for him a few years back. TC /ubbthreads/images/graemlins/cheers.gif

what grit, or 3" pad do u use, I tried this and it was too gritty with what I have.

 

[Tenacious C]

Here's a pic of the grinder I use and part of an aluminum bat I did with it and then candied over. I"m not sure what grit it is but it's pretty aggresive. Once you get that little sucker spining it makes a really nice swirl pattern.

 

[wickedpty]

Do you just swirl down the bat, or whatever you are doing. Or do yo do patterns. At my work we have some aluminum that has had this done to it, but you cant feel the cuts, t is perfectly smooth.

Well I don't think you would want it compleatly smooth. Those scratches and bumps actualy help with adhiesion.
