What is a Clear Coat?
A transparent layer of paint, a clear coat is applied over colored paint. Basically, it is a resin or paint that is colorless. It can make the metal object you are painting shiny making it look brand new again as well as protecting the paint so it will retain that look for a long time.
Other benefits of using it include adding depth to the color and protecting metal objects from UV ray light and the sun that can damage paint or make it fade. It can also help to protect the paint from being damaged by bird droppings, dirt, and rain which can be cleaned and quickly buffed out.
Types of Clear Coats
There are a lot of clear coat options on the market so it is important to know the difference so you can find the best one for your needs:
- Topcoat – Intended to be the last layer applied to paint, it can be very effective and easy to use giving the paint depth
- Turbo Coat – This is a fast drying clear coat that gives metal a glossy look.
- Glamour Coat – A slower drying clear coat, it allows more leveling and is less sensitive to moisture.
- Higher Solids Coat – Containing more additives, higher solids clear coat has a thicker film after the solvent has evaporated. With its thicker consistency, higher solids clear coats tend to dry slowly and are more expensive than other types.
- Euro Coats – Euro clear coats dry faster with heat but work just as well as the other types.
Important Facts to Consider
- Transparency – This is the most important consideration when choosing a clear coat. If you are interested in making the metal you are painting look new again, make sure to purchase a product that does not cover your base paint.
- Gloss Level – Also important to keep in mind, the gloss level should be more than 90 units so the metal you are painting will look shiny as just as good as a new one.
- Ease of Application – Since you are only adding another coat, it should not be difficult to apply. Choose an option with a nozzle that lets you spray on the metal’s surface evenly. This will guarantee that you won’t have any blotches on the surface and only a smooth glossy finish.
- Scratch Resistance – Metal can be vulnerable to scratches so applying another coat will guarantee an additional layer of protection to its surface. Look for a product that has scratch resistance and has UV protection for the most defense against the sun.
- Clean the Surface. Wipe away any paint particles or dust with a damp cloth from the metal’s surface. The surface needs to be cleaned correctly to make sure the clear coat adheres properly and won’t easily peel off.
- Apply Clear Coat. Using a paint sprayer or brush, evenly apply the first layer of clear coat. Once it is completely dry, apply a second one which will add another layer of protection helping to keep the coating last longer on the metal. Make sure to wait between 36 and 48 hours before you use your metal object and leave the object in a place where you won’t have to move it to prevent any accidental damage to the finished surface.
Frequently Asked Questions
Can you clear coat over bare metal?
You can use a clear coat on metal if you put more than just a few coats and make sure that there are no dry or thin spots. Using a high-end clear coat metal product will do the trick. The clear coat will also last longer if you use a product made by a reputable manufacturer with a good track record. If you do this you will see no signs of deterioration even after a year.
If in case you are using the clear coat to address bad flaking like those on car hoods, strip the paint off the hood down to the bare metal, metal condition it, and clean using a scuff pad until it looks like a well-brushed aluminum. After that you can apply the clear coat.
Having a good clear coat will weather the elements especially if you are using this for cars or stuff that you use outside the house. If you are thinking of using this on bicycles look at the type of bicycle that you own. Several bicycle companies produce bicycles that will hold up when you use a clear coat over steel but, as previously mentioned it does not work for some bicycles.
Does a clear coat prevent rust?
Clear coat protects metal against rusting when you apply at least two coats for good measure. Coating will prevent stains from dripping on the surfaces. Rusted metal is generally porous, check if the metal is completely clean and dry before you use a clear coat. If you want steel to last longer, use primer and paint before you apply a clear coat.
Moisture causes metal corrosion. A good clear coat will extend the life of the metal by sealing out moisture. When it comes to clear coat choose those in liquid form because powder coats tend to cause spots and flakes to form over rust. Check if the clear coats can withstand UV rays. Some formulas break down quickly and look like peeled skin when exposed to the sun beams.
How long does a clear coat last?
Clear coat will wear off over time because of dirt and debris. Take extra care to gently remove the dirt buildup because this can cause scratches to appear when you apply a clear coat.
The longevity of the clear coat depends on several factors like the type of product, condition of car paint, weather conditions, etc. Washing your car once a week and wax it once a month using quality products will make the clear coat last longer.
If you are using a clear coat on other projects generally it will last for a year with proper maintenance. This leaves the metal with that “wet look” shine. Car and metal items will last longer if you store it in places not exposed to moisture and weather elements. Temperature and humidity will affect the longevity of your clear coat.
How many coats of clear coat should I apply?
It is a good idea to use at least 2 to 3 clear coats to protect your metal from rust. If you are planning on using multiple coats it is a good idea to apply the first coat lightly. Doing this will prevent the metal from shrinking. Shrinkage causes cracks. You can go heavy when applying the succeeding clear coats after the first one.
Wait for the first layer to dry completely before you apply the second coat. Make sure that you spray or use the clear coat slowly and carefully to avoid drips and imperfections. Keep in mind that applying coats increases the thickness of the paint coat.
Should I sand between coats of clear coat?
Sanding is advisable because this helps diminish the clear coat until the surface is smooth. Polishing will help in smoothing out the scratches made by sandpaper. Sanding is a time-consuming process. Have enough time to start on your sanding project.
To smooth surfaces and remove small imperfections choose 80 to 120 grit sandpaper. However, if you are using this for finishing surfaces smoothly, use superfine sandpaper with 360 to 600 grit.
It may be a bit confusing choosing the best clear coat for your project, but once you know what to look for, you should easily be able to pick out the best product for what you have planned. Remember, you want good scratch and fade resistance as well as a good amount of transparency for any metal you are working on. Easy application and good protection from chemicals and UV rays are also great features to look for, so make sure to do your research before you head out to the stores.
