This is the replacement hood I tried to match to white plastic body in last years Cannonball
I started with Duplicolor Primer Sealer Grey
The scoop came from a 67 corvette and is also molded in white...
Then I sprayed Duplicolor Silver as a further barrier, from a tip I read on a forum somewhere..
There was a slight blush around the edges, but I thought the colour coat would cover...
Nope..
So I painted it something totally different...
Then I hit with clear, and the red came back again,..even worse, ...so black it is now...
So you can't really say it doesn't happen
