Great product so far, just installed roof and the paint quality seems to be good, using an impact to drive them in and heads of screws still have the paint
I paid a little extra for the ZXL Steelbinder Metal Roofing Screws. They worked great for drilling into the heavy gauge steel purlin. No pre-drilling necessary. Looks like they will hold up for many years to come.
Worked great for a tin roof and don't have to worry bout the sun ruining the rubber:)
