How can I make vertical and horizontal lines in Longtable thicker?

Question

For the following Longtable MWE, how can I make the third vertical line and the second horizontal line thicker than the other lines?

\documentclass[12pt, twoside]{article} 
\usepackage{longtable}
\begin{document}
\begin{longtable}[c]{|l|c|c|c|}
\hline
 & Col 2 & Col 3 & Col 4 \\ \hline
\endfirsthead
Row 2 & a & b & c \\ \hline
Row 3 & x & y & z \\ \hline
\end{longtable}
\end{document}

There is the accepted answer to the similar problem of yours here. Is it helpful? — Celdor, Jun 06 '22 at 01:41
Not quite... the closest to success was with with V{num}, but it highlighted that for some reason the edges of the cells in my table aren't perfectly lined up vertically. It may have worked in the MWE. — CraigS, Jun 06 '22 at 12:13
Well, solutions in the link seem to be working for me. You could try tabularray. It provides very intuitive interface to create complex tables where lines, spaces, alignments, etc. are easy to tune. You don't really need any other package but code may take a bit longer to compile. — Celdor, Jun 06 '22 at 12:33
Okay - thanks for the suggestions. Maybe there's something special about Longtable that's causing the issue. — CraigS, Jun 06 '22 at 14:45

Does the following example work for you

\documentclass[12pt, twoside]{article}
\usepackage{array}
\usepackage{longtable}
\usepackage{booktabs}
\begin{document}
\begin{longtable}{l | c | c !{\vrule width 2pt} c}
    \hline
    & Col 2 & Col 3 & Col 4 \
    \specialrule{.2em}{0em}{0em} \endhead
    \specialrule{.1em}{0em}{0em} \endfoot
    \specialrule{.2em}{0em}{0em} \endlastfoot
