Will clear powdercoat dull a polished finish?

i clear it one time and i got a cloud look to the metal ... but i used a high gloss urathane on it with no problem

very little if none and no polish ever
I've done lots of polish parts for motorcycles

Very little dulling to aluminum. it is the best thing to put on it i think.

I have read about the clear top coat dulling the chrome PC finishes, but I am wondering if it will do the same thing to a bright, highly-polished aluminum part? Anyone have any experience with this?

Thanks.
