Hi guys,
I'm currently in the middle of painting a plastic hull, which has been totally stripped back to its original plastic colour and painted with Halfords Grey primer.
Its had 5 good light coats now but there is still a blue band showing around the middle of the hull, about where the waterline is. The paint in this section just wouldn't totally strip back, I sanded for hours, used a plastic preparation cleaner and even tried a plastic-safe paint stripper, before washing the whole lot off and just painting over it.
The Grey simply isn't covering it even after the 5 coats. The hull is going to be antifoul red on the lower part, and then black on the upper section.
My question is this:
I'm going to use the Halfords Oxy-Red primer for the anti-foul, should I just try doing the red over the top all over, hoping that the darker colour would cover the underlining blue? or do I just keep sanding and priming with the grey until it goes (which would probably take about 10 coats at least looking at it)
I know I have prepared the hull properly for painting so I don't see that being the cause, I spent 3 days and a lot of hard work on it - it wasn't just a quick job I assure you.
Your help is appreciated.
Alex
