Paint for PCI Brackets?

[AMD Lover]

So i've been using some Krylon paint and it chipped really bad. I figured it would adhere because the brackets had a rough surface to them and the front and back sides of the bracket are fine however on the sides i think it was a little smoother and its just coming right off. Should i clear coat or should i sand down the areas that are chipping and try again?

Sanding it down should help, but you could start by using paint meant for plastics.

I used Krylon Fusion for plastic. It was a glossy paint. I haven't had any issues with chipping. Are you painting black brackets with white paint? You'll need a lot of coats.I would just sand and try again. It couldn't hurt to clear coat after you've reapplied the paint though.

How would that help?

Sanding or paint meant for plastics?

 

Usually paint sticks better to rougher surfaces so it doesn't just drip off.

Paint meant for plastics... kinda obvious why..

Yeah but the brackets are metal

Wow I was thinking of the wrong thing. (I'm sick, leave me be )

 

Just sand them a bit.

If my memory works right now, go with fine grit.

Fine. And don't scratch it up too much or else otherwise it'll show through the paint.

PCI brackets tend to have fairly tight fits depending on the design so thin coats are better, try using an extremely durable finish paint such as engine enamels or ceramics. Best thing to do is take steel wool or 220 grit sand paper and sand down parts, personally I like to lightly prime the parts before painting with topcoat to ensure adhesion.

Did you follow the directions on the can? Not meeting temperature and humidity levels can really mess up how durable paint is. Did you also wait 24 hours before messing with it? Dry paint is not cured paint.

 

Paint sticks to other paint very well, so I personally wouldn't bother using primer, it is more-so meant for bare metal. Lightly sanding it with 200 or higher grit sand paper to rough it up a bit will help.

 

Generally speaking, the longer time the directions say it takes to dry the more durable the paint will be. If you want a gloss finish, use appliance paint. It is probably the most durable paint you will find at a local hardware store, but IIRC the cure time is several days.

If you want to keep using krylon, then yes you should clear coat it for sure,  but I would look into using their high heat engine paint. That stuff is intense. However I would look into using Plastidip. I haven't used it myself, but I've heard good things about it.

People use it for cars all the time, and you can peal it off because it is like a spray on wrap.

I agree with the PlastiDip idea.  I just bought some myself for my rig and I can't wait to get started on mine.  The best part is that if you don't like it, you can always peel it off and start over.
