    Powdercoating Mesh..

    Hey guys just got back from the blasters/powder coaters.

    I took my Simmons V4 mesh centers down to be stripped and powder coated, but I've been warned of a bit of a problem...

    Stripping them will be ok, they were originally painted, so now they will spend at least 3 days soaking in chemical stripper. If that works, great! but if they are still a bit mucky, they will then be glass blasted.

    When I spoke to the guy who does the PC'ing he told me he had done several Simmons wheels before and had run into a problem on some..
    Because of the intricate mesh pattern the electro magnetically charged metal has problems attracting the powder in the tight corners and in the mesh. Because some parts of the metal are so close together (see picture below) they contradict each other and it may not work.

    He said in the cases he's had before, some have come out great, perfect, and others have failed to seal in the grooves, sometimes two might work, two might not.. so there is a risk.

    Here is a picture showing where exactly he said there might be a problem:



    SO is there anyone that has had experience with this type of thing? I don't mean podercoating just any wheel, but in particular mesh wheels or other complicated patterns? How did they turn out?

    My other option is to paint them myself, I am confident I can get an as good or better finish, but it will certainly not be as resistant to chipping, or brake dust stains. And I really don't want to have to paint these again for a long time..

    I actually have only coated 2 weave types, stock 14" weaves and got pretty good coverage. The problem he's talking about is called faraday cages not sure on spelling, sounds like that though. The way the negative charge works makes a area of low charge in sharp corners like that.

    pre-heating the wheels to 200*F or so, taking out of oven then spraying helps get coverage. Gets better adhesion. have also tried it with the wheels so hot the powder goes liquidy when it hits. Great for coverage, but you're basically just painting at that point, can't brush the powder off and start over if there's a problem.

    Tell him to hot flock em, thats the terminology. If you dont wanna risk it get em painted
