Spray paint finish issues

[-S-]

Anyone know why im getting this result? Bad batch of paint or some mistake i made?

 

I'm thinking it was dust as i was doing it outdoor? And the floor i was spraying on had " black dust" as per the pic. ..

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.

No . Meant to be just black. Using duplicolor caliper spray paint... guess it's back to step 1 again. Sigh...

Looks like wrinkle paint though lol ... meh...

Spray on cardboard and away from dirt.

Looks like a shit load of dirt on the paint.

Spraying on surfaces that are to hot will result in bubbling. Happens to me often because is spray in the sun.

Yeah i guess it was dirt/dust from the wind too when i went for a break lol .. because the floor had some evidence of dust when i swept it with my feet. .. i doubt it was hot as i wasnt under the sun though. .. ok guess it's not the paint!

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.

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.

could be a bad/partially blocked nozzle, i had a similar issue with a spray gun once. chucked it, thats what i get for buying cheap crap

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.

Oh. .. btw i did use caliper cleaner as well and i thought that removes grease and wax. .. oh and lucky u don't need to prime. .. guess i should've bought vht as well... save me some coin
