Painted my Intake
Painted my Intake Didn't come out exactly how I wanted. Maybe if I sand the clear in a few days it will look a little better. What I learned though, is that I suck at painting and next time will let someone else do it.
Sanding these intakes smooth is a PITA because of all the nooks and crannies. Best solution I've found is a quick sand for some mechanical adhesion, 2 coats of adhesion promoter, then a couple pretty thick coats of high build primer before laying on base. Comes out super smooth and slick:

Edited to add the following.
I would advise following Parbreak's "how to" very closely. Some advocate lots of clear. I think that may have caused some minor problems for me. Also, do not let base and clear over-dry between coats. If for some reason you are interrupted and you cannot lay all your base and clear down at one time (allowing the curing times Parbreak recommends), scuff it with 400 grit and start over with base. My first mistake was not properly scuffing the base I let dry so I could remove a mark I made in the wet paint. The second might be applying too much clear.

I sanded the absolute hell out of it. You suggested a minumum of 400 grit if using high build primer - I went to 1000. I sanded the high build primer super smooth as well.
The silver base came out pretty good I think. I just wish I could watch someone paint something plastic like this once. I'm so afraid that I'm going to spray it on too thick, so I do it light and spread it out over 6 or 7 coats instead of 3 or 4. Maybe I'm doing too much misting which is causing it to be uneven.
Either way, the real problems arose when I added the anodized blue over the silver. It didn't come out nearly as nice as when done on my calipers. In fact, the first time I did the blue it was so rough the top coat would crumble off if you touched it. So I waited a week, then sanded it smooth again until some silver could be seen again. This time I think I laid it on too thick
I don't know. It looks like I was drunk and half-assed it when I really spent A LOT of time on it. Depressing.

That is something weird with the anodized blue though. Was it the same type of paint you used as the silver base?

And the anadodized blue is a Duplicolor Metalcast. The silver is an Acrylic Lacquer Duplicolor.

Verdad Gallardo You can get like a paint thinner/aircraft stripper. You could also sand it all off, but that would clog things up. I would go a chemical route. It will all curd right up and be really easy to remove. As for the paint, maybe the Duplicolor Metalcast is having a problem with the plastic. I'm not too familiar with it. I assume it can be used on plastic right, if properly prepped?
. But hey aleast you tried.

The almighty Paint Fumes Director Parbreak suggested using Lacquer Thinner and wiping it off. Here is a thread with that advice.

So when I use stripper/thinner, will that just take off the paint or does that take off primer as well?

Use aircraft remover.It will take off everything. Thinner will probably work alright but aircraft remover is a little easier.Its sometimes pretty messy though thats why I would just scuff it up good and reprime. Since its pretty fresh paint though it should eat it off pretty easily. If you have a high pressure washer I would spray the aircraft remover on the intake let the paint bubble up a little bit then spray off with water. Repeat as much as needed till your done. Hopefully not too much sanding.
How do you guys spray the intakes, with a gun sprayer or can paint?
BTW, I used that same blue paint for one of my projects, and came out alright.

I would not use a chemical stripper, or thinner!!!
It could soften the plastic and ruin the intake.
Use what you already have on there as a filler.
So all you need to do is just sand it smooth with 320 or 400 then apply 2 coats of a high build primer, then sand smooth.
If you still see dimples and it is not completely smooth then re-apply more primer and then sand smooth again. The smoother the primer is the smoother the base and clear will lay down!
Try to think of primer as liquid filler!
