Looks like it was too hot when you sprayed, the powder is paint that has had the thinners used to transport it out of the can and onto the part evaporate on exposure to air, and dry out the paint.  This makes a powder that mixes with the rest of the paint and goes clumpy like that.

Try and spray in the shade in an area with minimal wind. Also before you start spraying let the can sit in some hot water for a couple mins then shake the can for a minute before spraying.

Do a couple of light coats, then do heavier coats. I used a whole 2 cans for 4 calipers and had a small amount left over for 4 brake rotors. Ended up doing like 8 coats all up for the calipers.20170129_210945.jpeg

My top 3 least favourite DIY's on the car:

  1. Removing steel sleeved bushes
  2. Sorting electrical gremlins
  3. Painting parts

I've done 2 sets of wheels (Just Don't Do It) and my roof and boot lip wings and they're never perfect. I reckon beyond what others have said above, you really need an enclosed indoor space with minimal dust and airflow to get a decent finish. I've done most of my painting outside and the amount of dust and bugs and crap in the air is just amazing, not really conducive to a great result.

Also body shops use ovens to cure the paint at the correct temperature, to achieve a good finish and seal especially for the clear coat. Very hard to do at home.

Looks good. Did u prime it first? Looks like it's clear coated.
I'm just going to prime then paint mine that's it

Nahh i didnt prime or clear coat. I used the vht gloss black caliper paint. For prep i just sanded, used brake clean and followed with wax and grease remover. The vht caliper paint label didn't say anything about primer so i assumed you dont need it.

Here's a better pic, a bit dirty though.

    • My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.
    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
