Introduced in 1978, the VB Commodore marked Holden&#8217;s transition from the large Kingswood platform to a more modern, European-inspired design based on the Opel Rekord and Senator. The VC followed in 1980, while the VH arrived in 1981 and became one of Holden&#8217;s most successful early Commodore models.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Today, these first-generation Commodores are highly sought after by collectors, restorers and enthusiasts. However, one issue continues to affect almost every surviving example: rust.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Despite improvements in manufacturing and corrosion protection compared with earlier Holdens, VB, VC and VH Commodores are now more than 40 years old. Water traps, poor drainage, damaged paint and decades of Australian conditions have allowed rust to become a major concern.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In many cases, rust damage is far more serious than engine, transmission or suspension problems because structural repairs can be extremely expensive and time-consuming.<\/p>\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;Commodore<\/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.

Holdens, early Commodores still suffered from several rust-prone areas.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Common Causes<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Water retention<\/li>\n\n\n\n<li>Blocked drain holes<\/li>\n\n\n\n<li>Damaged paint<\/li>\n\n\n\n<li>Moisture trapped in seams<\/li>\n\n\n\n<li>Poor previous repairs<\/li>\n\n\n\n<li>Coastal environments<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Many vehicles now have multiple rust issues developing simultaneously.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Front Windscreen Rust<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">One of the most common rust areas on VB, VC and VH Commodores is around the windscreen.<\/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<\/li>\n\n\n\n<li>Rust stains<\/li>\n\n\n\n<li>Water leaks<\/li>\n\n\n\n<li>Visible corrosion under rubber seals<\/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\">Moisture becomes trapped beneath the windscreen rubber and slowly attacks the metal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In severe cases, rust can spread into the A-pillars.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Rear Windscreen Rust<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">The rear window opening is equally susceptible.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Common Symptoms<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Water leaks into boot<\/li>\n\n\n\n<li>Rust bubbles around glass<\/li>\n\n\n\n<li>Damp carpet<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Inspection Tips<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Carefully inspect beneath the rubber seal and inside the boot area.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Many vehicles hide significant rust beneath apparently good paint.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Plenum Chamber Rust<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">The plenum chamber sits beneath the windscreen and supplies fresh air to the cabin.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why It Rusts<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Leaves accumulate<\/li>\n\n\n\n<li>Drain holes block<\/li>\n\n\n\n<li>Water becomes trapped<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Symptoms<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Water leaks inside cabin<\/li>\n\n\n\n<li>Rust around firewall<\/li>\n\n\n\n<li>Damp carpets<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Repairing severe plenum rust can be labour intensive.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Firewall Rust<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Rust frequently develops where water becomes trapped between panels.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Common Areas<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Plenum joins<\/li>\n\n\n\n<li>Heater box openings<\/li>\n\n\n\n<li>Wiring pass-throughs<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Why It Matters<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Firewall rust can be difficult to access and repair properly.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Front Guard Rust<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Front guards are among the first visible areas to show corrosion.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Common Locations<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Lower rear guard sections<\/li>\n\n\n\n<li>Wheel arch lips<\/li>\n\n\n\n<li>Guard mounting points<\/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>Mud accumulation<\/li>\n\n\n\n<li>Moisture retention<\/li>\n\n\n\n<li>Damaged paint<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Replacement guards are becoming increasingly difficult to source.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Best Rust Converter<\/h1>\n\n\n\n<h2
