Seal and color stress cracks fast with no sanding, no mixing, no odor. MagicEzy Hairline Fix is a colored one part, nano sealant that fills and seals damage at both structural and cosmetic level easily.
Of the 11 colors offered by the manufacturer, the snow white we offer is the best match to your Catalina. The color of your boat has changed over time, more in some places than others. But the snow white will be very close and gel coat cracks are so narrow that the repair will be barely visible.
Sold in 0.43 fl oz tube with built in applicator and in Snow White color.
Note: In our experience, even Hairline Fix has a limit as to the minimum width of crack it will penetrate. If the crack is only one or two thousandths of an inch wide, even this product wont fill it. But for the majority or cracks it works great.
