Sorry, forgot your name at OHW., Recently I bought a 12/12 deal on paint. Came across a weird issue. Had a part (simple half helmet) pre painted ohw silver. Did a bad dip. Bought the 12/12 to get more silver for rebase. Silver can out of new batch, approx 7-8 coats later REALLY, 7-8 ; almost half the can on a half helmet in a wtf moment because it just wouldn't cover. Looked almost like clear until the third coat or so. Is it possible I had a mismarked can of inter coat metallic? It really seemed almost like a sort of metallic tinted clear. I can still make out the bad dip I was trying to cover, even with all that paint. And yes it was A very well shaken can too. I do know how well metallics will lay down As long as they're shaken thoroughly.
In fact, you know when you first do a waste spray to clear propellant it often comes out clear -ish before to pigment starts flowing? It's like that but not a lot of color lays down.
