Finishing/cleaning clearcoat?

post #1 of 7
Thread Starter 
So I put on my final clear coat and the rustoleum stuff I used has terrible overspray, to the point where you get overspray on the part you're actually painting lol.

Right now it has had a couple days to cure, but I'm planning on letting it cure for at least a week if not more. The problem is right now there is overspray all over it especially the inside of the back (where the pcie slots are). Tack rags pick it up, but it's very hard to get in the little tiny spaces.

Two questions,

Will the overspray stick to the paintjob if I leave it there?

How would I clean it off? Tack rags leave residue (or whatever it's called) behind so I was going to wash the whole thing in soapy water like I have done a few times before painting. The problem is I don't want that to mess with my paintjob which hasn't entirely cured yet, but on the other hand I don't want to just leave it and have the overspray permanently stick to the case (leaving white specks all over it).

I appreciate any advice .

Are you trying to remove paint off of a bare metal surface or a painted/finished surface?

edit: oh I think I get it now, you need to clean up a puddle of overspray? Just wiping it up won't yield very good results...

Is your finish flat or glossy?

Uhm. The whole case is painted with matte clear. It's all fine except the last coat left some fine overspray that settled on the rest of the case. It's not really painted on, it's just like a thin layer of dust.

How were you spraying it? You should always spray in even short bursts to prevent the nozzle from building up with paint and causing it to spray all over. And cover up any areas you don't want to be painted on.

If you want you can just apply another coat in the area that was hit with over spray and cover up/tape off the clear coated area you just did.

No I did and everything came out fine. I was painting the whole case after it was assembled (was not possible to assemble it without ruining any paint job).

If I painted over the overspray it would just make permanent peaks in my paint which is exactly what I want to avoid. You'd be surprised how much overspray this stuff puts out. If I painted the tower and the side panel was five feet away, there would be a fine layer of dust on it after. I had no problem with just about any other paint.

My question really is, will soapy water have any bad effects on paint that isn't completely cured (most of the way, but like I said, only a few days)?

(Paint spray will float/carry a pretty good distance. Paint one piece at a time, or a lot of them in the same time) to avoid overspray. For future reference, if you have a fully painted piece like a side panel, move it otu of the way when you paint another piece.)

Soap and water won't bother your cured paint coat. Though it won't take that overspray off entirely either. You're best option is to take some fine sand paper (>1000 grit) and LIGHTLY sand the overspray off. Pretty much use the sand paper to wipe the surface. Then clean off the sanding dust with a tack rag. And finally wipe it down with some alcohol and spray another coat of clear on it. The last coat will fill over the sanding marks from the sandpaper and leave you with an even finish.

If the paint under your clear is cured, you'll have a much easier time doing this. If it is just a misting of paint that went places it shouldn't, try isopropyl, and if that doesn't do it, a QUICK wipe with goof off. There is a possibility that the goof off will slightly change the original layer's surface finish. If it is a gloss, you can just polish it right back out if this happens. If it is a flat... I'd say it really depends on the paint. Try it in an inconspicuous area first.

The goof off will soften the paint. If you do it with the right technique it should just take off that surface mist and not do anything to the original coat (ie, a quick polish should make it like new, if needed at all).
