Inside of valve cover slightly powder coated

[AZDSM]

I feel like such an idiot for never really noticing this when I had this work done several months ago. I'm sure I saw it, but it just didn't click with me. Probably too excited over how cool it looked. The place specializes in automotive parts, but yeah. Obviously little to no masking was done.

EDIT: I called the place that did the work (was expecting voicemail) and spoke with the owner who did it. He basically said that they generally do not mask off the inside since there is so much cleaning and prepping involved and that the power coating will not come off... sure sounds good in theory, but we all know anything is possible. He also mentioned something about Nascar powder coating the inside of their engines... didn't really know what else to say. So now I'm debating what I should do.

Is powdercoat on the inside bad? I get mixed answers searching all sorts of topics on google.

Some people have the sides or skirts of there pistons coated, and even though i am not sure, if the same chemicals used on the pistons, are the same as the ones used to paint valve covers, if they are then i think you would be fine, i may very well be wrong. The under belly of the VC does not make contact with any moving/ rotating parts, so only heat and oil could possibly remove the paint. I think your ok, but i guess you could try to clean it up if you feel the need.

Damn too bad you noticed so late, I would have gone down there and demanded a new valve cover painted black professionally like I payed for, if I wanted it to look like my little sister did it I would have bought some paint and given her my spray gun.... So unprofessional to not even bother to mask, thats like the first thing you learn when painting.... If I knew for a fact it was bad for the car I would go in there and smack the guy around! Sorry I cant give you a definite answer of weather or not its okay.

Someone suggested to me that I remove the baffles and find evidence of beading/sand and try and have them fix it, but I don't see anything being resolved from that. I'd much rather put it in the hands of someone professionally trained from this community to do it right (which I regret not doing the first time).

So at the suggestion of greengoblin I used Simple Green Extreme to coat the inside of the VC. Let it pool inside the baffles and sat for about 5-10 mins. The hope was to see what would come out when I dumped it all out. Here's the result...

Now I'm no expert or anything, but I do believe what I am seeing isn't something a Valve Cover should normally excrete. The black "sediment" on the lip of the bucket is what sits at the bottom of the bucket. It had a very fine grainy feel to it. So suffice to say I think at this point I'm taking the bucket and the valve cover back to the shop that powder coated this and see what they will do about it.
