To Remove or Not to Remove?

As car, van, boat and machinery owners, we understand the importance of rust prevention. It’s the shield that protects our vehicles from the relentless onslaught of corrosion. But when it comes to applying a new rust prevention coating, a common dilemma arises: should you remove the existing coating first, or simply apply the new one over it?

The decision isn’t always straightforward. It depends on a variety of factors, including the condition of your vehicle, the extent of existing rust, and even your gut feeling. Let’s look into this decision-making process to help you make the right choice for you.

Assessing the Current Situation

The first step is to assess the condition of the existing rust prevention coating. Is it still intact and doing its job effectively? If so, you may not need to remove it entirely. However, if you notice any signs of weakness, such as flaking or peeling coming from underneath, or if the coating has been compromised in any way, it’s best to remove it before applying a new one.

Extent of Existing Rust

Consider the extent of existing rust on your vehicle. If it’s minimal and localised, you may be able to scrub it away before applying a new coating. In this case, removing the old coating entirely may also not be necessary. However, if the rust is widespread or severe, it’s crucial to address it properly before applying any new coatings. Be sure to check from both sides of the metal too. 

Gut Feeling and Expert Advice

Sometimes, your gut feeling can guide you in the right direction. If you have doubts about the effectiveness of the existing coating or if you’re unsure whether it’s compatible with the new one you plan to apply, it may be wise to remove it entirely and start from scratch.

The decision to remove or not to remove the existing rust prevention coating should not be taken lightly. While leaving it intact may save time and effort, removing it can ensure that your new coating adheres properly and provides maximum protection against corrosion. Assess the condition of your vehicle, consider the extent of existing rust, trust your gut feeling, and seek expert advice if needed. 

With the right approach, you can make an informed decision that keeps your prized possessions rust-free for years to come. And remember, you can always adopt a ‘watch and wait’ approach in the first instance.
