Any of you know any tricks for minimizing flop?
Spraying base more wet or drier make a difference?
I'm still having problems with some silvers that I can't get a good match
because of the flop. There's got to be a something to help, so help!
Small amounts of white will lighten the flop as well.
Since this has been brought up again, I’ve forgotten to ask in the previous thread. What does adding white pearl to a silver do?
I remember being discussed in the old SPI forum but I cannot remember the right answer to that and I have searched the forum but I come up empty.
What are you calling a control coat?I've said it before and I will again. Try doing a control coat even for butt matches. It will "soften" the flop.
When you get coverage, reduce (I use the intercoat) what's left in the cup by 1:1, drop pressure down 5 or so pounds, pull back your distance a few inches and spray the edges. Let it flash, reduce again to the same ratio and repeat. It helps the metallics to blend better. Eliminates sand piling which leads to darker flop. This is my opinion. I'd love to hear other options.What are you calling a control coat?

Drop coat is what I know it as. Like when doing acrylic's the last coat on colors like silver sometimes need a final drop coat to help orient the metallic.
but I have had to change metallics, or the ratio of one metallic to another, in extreme cases. White pearl will also lighten the flop without changing the face too much. White toner will change the face very quickly, making it milky, so you have to be careful. Very little you can do with technique, as Chris said, to change the side tone much.
Same as "halo". Flakes build up where you stop your gun travel and make the dark rings.I got to try that, thanks.
You say spray the edges, do you spray the rest of the new base too?
And what is "sand piling"?
It's been my experience that the only way is to adjust it is in the mixing process. What brand of paint is it? When I had to use Omni Plus it was sometimes an issue. Do you mix it or are you getting it from your jobber? If you mix you could try adding some more flop control agent or flattener like we discussed in that other thread.
As far as spray techniques some may say different but the flop is the flop and there really isn't much technique wise that you can do to change it. The only effective way to change it is to add or subtract the amount of flop control in the mix. If you have SPI flattener try adding 1-2% by volume and see what that does.
Thanks, and by the way, the one giving me trouble right now is Omni.
It is not really the size of the flake, but the side tone that particular flake has. There is usually 2 toners with the same flake size, but different side tones. Most of the time there is an indicator of some sort on the toner can that will tell you which way, light to dark, it will move the side tone. Just did a Cadillac side today, code 994l. I had 3 spray out cards, 1 was std., and 2 alternates. The face was on the std. formula was near perfect, but the side tone was way too dark. To make that formula match the side tone, I would have to leave out most or all of the black toner, which would change the face. It was far enough off that adding more flattener was not an option. One of the alternates had a near perfect side tone, but the face was too yellow. The other alternate had a yellow face and the side tone was slightly dark. What I will do is use the alternate with the good side tone and just leave a little bit of the toner out that is making the face too yellow, because it is the easiest fix of the 3 formulas I had spray outs on. (this code had standard and 11 alternates!). If I have a choice between a formula with a good face or a good side tone, I will almost always choose the good side tone because it will blend easier, especially if you don't have a full panel to make your blend. Sorry for the long winded reply.So, does the metallic size play a role? I would think so, but how?
Does smaller metallic help or hurt with flop?
This is all good stuff
