Posted by admin on August 23rd, 2009 at 07:45am
Plz help, its the first time it happened to me. I first sanded the rough cast aluminum with 180,220,320,400. Now at 400 girt i can see it coming better.But at a certain spot there is like a birth mark that is a darker looking color like it just came out from under the aluminum when i was sanding. Anybody got a clue what this would be and how to fix it. I keep on sanding it but it stays the same color not like the rest of the surrounded area help.Thank u i’ll show u a pic ,but if anybody ran through this before can u tell me what i should do.
