What is the best type of lubricant to use on a metal garage door? I'm
referring to the rollers and other moving parts, and possibly the rollup
spring.

If I'm not mistaken, you should not lubricate the roller tracks.

Should I use WD40? I also have some silicone lubricant in a spray can
that
I could use.

Thanks.

WD-40 is not a lube. Use motor oil and squirt some across the top of the
springs once a year.
