You may be surprised at how easy a synthetic paint sealant is to apply. If you can put wax on then you will certainly be able to apply a sealant. It can be applied by hand or you can use a machine. Sealants are liquids and are therefore very easy to work with. Your main aim should be to apply it both thinly and uniformly. How to apply paint sealant by hand Here are the steps that you should follow to apply sealant by hand. Make sure that the paint surface that you are covering is completely clean. Pour a few drops of sealant onto an applicator pad. This should be made of foam or microfiber. Make contact with the paint lightly and spread the sealant across the paint thinly. Some people prefer a circular motion but others prefer a cross hatch. You must cover all the paint so overlap each pass as you work across each panel of your car. Leave the sealant in place for the period of time specified by the manufacturer. This is usually between 10 and 20 minutes. For wipe on wipe off sealants, you will have to buff excess sealant using a microfiber cloth. Let the sealant cure before you apply another coat. This could be up to a few hours. How to apply paint sealant by machine Here are the steps that you should follow to apply sealant using a dual action random orbital polisher. Fit a fresh finishing pad to the machine. Apply a couple of drops of sealant onto the finishing pad. With the machine off, use the pad to spread some car paint sealer around. Select a low speed and spread the sealant evenly. Select a high speed and work the sealant in at around five inches per second and overlap each pass. While the pad is still in contact with the paint, turn the buffer off. This will prevent slinging. For wipe on wipe off sealants, after 10 or 20 minutes (check the instructions) buff off left-over sealant by placing a microfiber cloth over the top of a new buffing pad. The sealant must cure before you can apply another coat.
