Spanning from 1971 through to 1984, these models covered everything from family sedans and wagons to utilities, panel vans, luxury Statesmans and commercial WB models.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">They are also among the most popular classic Holdens on the road today. HQ Monaros, HZ Sandmans, WB Statesmans and Kingswoods continue to attract enthusiasts thanks to their timeless styling, strong mechanicals and excellent parts availability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unfortunately, like most Australian vehicles built before modern rustproofing standards, corrosion is one of the biggest threats to their survival. Many seemingly tidy cars hide extensive rust damage beneath paint, body filler and underbody coatings.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Whether you&#8217;re looking to buy, restore or maintain one of these classics, understanding where rust develops is critical.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Why HQ-WB Holdens Rust<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Several factors contribute to corrosion in these vehicles.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Common Causes<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Limited factory rust protection<\/li>\n\n\n\n<li>Moisture trapped inside body cavities<\/li>\n\n\n\n<li>Poor drainage design<\/li>\n\n\n\n<li>Australian coastal conditions<\/li>\n\n\n\n<li>Dirt accumulation in seams and panels<\/li>\n\n\n\n<li>Previous poor-quality repairs<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Even cars that have spent most of their lives in dry climates can develop hidden rust after decades of use.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Front Guards and Lower Mud Traps<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">One of the first places rust appears is behind the front wheels.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Symptoms<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Bubbling paint near guard bottoms<\/li>\n\n\n\n<li>Rust staining around seams<\/li>\n\n\n\n<li>Soft metal behind wheel arch<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Why It Happens<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Mud, dirt and moisture collect behind the lower section of the front guards. Over time, this trapped debris holds moisture against the metal and corrosion develops from the inside out.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Many otherwise clean HQ-WB Holdens require repairs in this area.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Doors and Door Bottoms<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Door rust is extremely common throughout the HQ-WB range.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Symptoms<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Bubbling paint along lower edge<\/li>\n\n\n\n<li>Water draining from doors<\/li>\n\n\n\n<li>Swollen seams<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Causes<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Blocked drain holes<\/li>\n\n\n\n<li>Condensation inside doors<\/li>\n\n\n\n<li>Water ingress through window seals<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The problem is often hidden until significant damage has already occurred.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Best Rust Converter<\/h1>\n\n\n\n<h2 class=\"wp-block-heading\">Recommended Product: Fertan Rust Converter<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Benefits<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Chemically neutralises rust<\/li>\n\n\n\n<li>Penetrates difficult areas<\/li>\n\n\n\n<li>Suitable for restoration work<\/li>\n\n\n\n<li>Can be painted over after treatment<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Best For<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Surface rust<\/li>\n\n\n\n<li>Internal panel treatment<\/li>\n\n\n\n<li>Early-stage corrosion<\/li>\n<\/ul>\n\n\n<div id=\"fu_ebay_0\"><!-- Presentation: cols = 4, rows = 2, slideshow = Manual, slides = 3, slideId = 0 --><div class=\"fu_ebay_results_container \">\n<h5 class=\"fu_ebay_results_title\" style=\"display: block !important;\">\n<a name=\"fu_slidetop_0\"><\/a><a href=\"https:\/\/www.ebay.com.au\/?mkcid=1&#038;mkrid=705-53470-19255-0&#038;siteid=15&#038;campid=5339152561&#038;customid=5339151688&#038;toolid=10049&#038;mkevt=1\" class=\"fu_ebay\" style=\"display:inline !important;\" rel=\"nofollow\" target=\"_blank\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/australianholden.com\/wp-content\/plugins\/fast-ebay-listings\/US\/Right_Now_108x45.gif?resize=108%2C45&#038;ssl=1\" style=\"border:0;display:block !important;\" width=\"108\" height=\"45\" alt=\"Right Now on eBay\"\/><\/a>&nbsp;Fertan Rust Converter<\/h5>\nLoading&#8230;<\/div>\n<\/div>\n<script>\n<!--\nvar content_fu_ebay_0 = null;\nvar waitForDepends_fu_ebay_0 = setInterval(function () {\n  if (typeof jQuery !== \"undefined\") {\n  if (window.fu_is_bot_useragent !== undefined) {\n    clearInterval(waitForDepends_fu_ebay_0);\n    if (typeof jQuery.ajax == \"undefined\") {\n      console.log(\"Fast eBay Listings: jQuery.ajax missing.

While mechanical components are generally robust and readily available, serious corrosion can quickly turn a promising project into an expensive restoration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The good news is that these vehicles rust in predictable places. Knowing where to inspect and how to treat early corrosion can save thousands of dollars and preserve some of Australia&#8217;s most iconic Holdens for future generations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Whether you&#8217;re restoring a Monaro, maintaining a Kingswood or hunting for a WB ute, a thorough rust inspection should always be your first priority. Finding rust early is far easier\u2014and far cheaper\u2014than repairing it later.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Related Articles<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/australianholden.com\/index.php\/2026\/06\/17\/how-to-inspect-a-hq-hj-hx-hz-or-wb-holden-before-buying\/\" type=\"post\" id=\"7318\">How to Inspect an HQ Holden Before Buying<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/australianholden.com\/index.php\/2026\/06\/20\/holden-202-engine-issues-explained\/\" type=\"post\" id=\"7311\">Holden 202 Engine Issues Explained<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/australianholden.com\/index.php\/2026\/06\/17\/trimatic-common-issues-explained\/\" type=\"post\" id=\"7314\">Trimatic Common Issues Explained<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/australianholden.com\/index.php\/2026\/06\/17\/hq-hj-hx-hz-and-wb-holden-electrical-problems\/\" type=\"post\" id=\"7332\">HQ HJ HX HZ WB Holden Electrical Problems<\/a><\/li>\n\n\n\n<li>Best Rust Prevention Products for Classic Holdens<\/li>\n\n\n\n<li><a href=\"https:\/\/australianholden.com\/index.php\/2026\/06\/16\/early-holden-rust-problems-common-trouble-spots-warning-signs-and-how-to-fix-them\/\" type=\"post\" id=\"7191\">Early Holden Rust Problems<\/a><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The HQ, HJ, HX, HZ and WB Holden range represents one of the most successful vehicle families ever produced in Australia.
