Hi,

Have a few screw 1/4" dia. approx. screw holes (screws long gone) in my
wood siding.

What's a good product to fill them up with?

I remember small tubes of "Plastic Wood"
Would this be the stuff to use, or is there something better now ?

Would have to be available in small tubes, as I onle a few holes to fill in.

Thanks,
Bob
