Flat Clears

[John Diakonis]

I'm trying to experiment with PPG 2060 and PPG One Choice SU 4985 Matting agent. I'm finding out that I can't really get a flat clear that will not burnish to some degree. On the 2060 my fingernail was able to burnish. All the bike manufactures have some type of matt clear so it's definitly possible.
I started with the smallest amount of all the parts not wanting to waste too much. Most receipes call for enough to make a sprayable quart of clear solution. I'm not wasting that much to experient and I won't even need that much when doing parts.The other thing that happens with the 4985 is I get this chaulky, milky appearance.I used less than recommended but it still burnished. At this pointe I wouldn't even mind more of a satin look. Any suggestions on technique or even a product that will do what I need? A matt look with no burnishing? Thanks.

that wouldn't polish. I tape off matt surfaces when I do cars because a touch of the polisher shines them permanently. These are typically flat black stripes but I'd guess the same would apply to clear.

The more it is hard (cured) the less it will have a tendency to burnish as you mentionned. Those clears will take longer to harden, weeks in fact to reach their full hardened potential.

As Robert mentionned, any matte clear will polish to a certain point while remaining quite milky but shiny. It's the nature of the beast. Be carefull of what you compare it to as many motorcycle parts are not painted but powder coated or black anodized for matte finishes...

Thanks Robert and Serge, The parts that I'm talking about are painted plastic body parts not metal parts. I'm sure some metal is powdercoated. These are metallics that have a clear matte applied to them.

Lesonal makes a matte clear that works well, but its probably the same deal as what your using. And when you speak about digging your nail into it...like Serge said...it will take atleast 3-4 days to harden before its hard enough to resist your nail. With the lesonal matte clear you mix matte clear with the regular clear depending on how much of a gloss you want. You can use straight matte for a satin finish...then you can add some regular clear to it to make like an egg shell look, and so on and so forth.

If the project is worth the expense you might want to try some Glasurit pre-flattened clear. It comes in Semi-Gloss (#923-55) and Matte Elastified Clear (#923-57) I use the 55 frequently and it's pretty resistant to marking. Mercedes uses the 55 to spray the bottom of a lot of their tu-tone cars so it's pretty bullet proof. I've been painting some furniture with the 55 and it's working quite well but you can't polish it or it will get a permanent shine.

I'm looking for the same thing in an epoxy?
