    Paint bleed under masking tape

    Hi
    I’ve recently been doing some work on my grandson’s model railway rolling stock. He wanted to change the livery on the coaches to a striped one.

    I masked off the stripes in stages as I went through the 3 colours, using Tamiya masking tape after first washing the items carefully.

    I primed with Halfords Grey primer (original formula not the more recent changed one) and airbrushed each colour in sequence using Tamiya Gloss Acrylics :Tamiya thinner 1:1.

    I was disappointed on removing the masking that the Tamiya tape had allowed the colours to bleed onto the layer beneath. Trying to correct this using the same but fresh tape, and really firming it down along the relevant edges was unsuccessful- I could even see the spray going up underneath by capillary action while airbrushing.

    it’s almost as if the Tamiya tape doesn’t bond well to Tamiya Gloss paint.

    Any thoughts? Anything more reliable than Tamya tape?

    To stop bleeding use humbrol clear..... Just brush it along the edge of the tape.... It will seal the edge
