Topic: Polish Marks

Can anyone give me advice on how to prevent polish marks from occurring?  Does humidity affects it?

Re: Polish Marks

Can you be more specific?  Are these swirls from the polishing process?  Or some sort of haze under the paint that is showing through?  Please provide more info.

Re: Polish Marks

Sir Dustin,

this is our process:

preparation -> painting  -> baking of parts in an oven -> spot sanding using trisac (2000 grit) -> paint curing for at least 5 hours -> polishing -> quality inspection -> delivery.

but it was being observed that polish marks as well as sanding marks manisfest after we export our products in our customer (Thailand plant); though during our process, the parts passed through a 300% inspection --- 100% before delivery, 100% at dock and 100% at port.  So we are now having our researches why poor polish and sanding marks occur in our customer side?  Does humidity affect it since shipping of parts going to Thailand is around 8 days?  Is it the oven temperature?  Is it the paint we are using?

hope you will help me with this... thank you very much.
