Hi,I am repainting a 1957 BT 35 HP.I have chose to use a Duplicolor Ford 257 Medium Blue.It is in my estimation a close match to the Poly-Chromatic Blue,but at $5.00 a can rather than 13.99 + S&H a can.My question is is it ok to use this paint on the power head itself? Will it hold up to the heat? Was the original paint a high heat paint or was it not nessessary? Has anyone used this type of paint ,Duplicolor Acrylic Laquer? Thanks Jim
