PRESTO® GUN BLUE PEN
£11.00p for two
Condition: New, in packaging
Perfect for repairing scratches.
Quickly and easily penetrates hard steel.
Use like a marking pen.
Made in the USA.
The Presto Gun Blue Pen quickly and easily penetrates hard steel and gives a durable blue-black finish that won’t rub off.
Use like a marking pen for one-coat coverage on non-stainless steels.
For best results use a degreasing cleaner (or washing up liquid) prior to applying the blueing pen.
To test the pen, it's best to apply to a piece of white paper, as it is not obvious during usual use.
