How to apply and remove the BLACKFIRE SiO2 Spray Sealant
Before I get into the step-by-step directions, first I want to share my technique for applying and removing spray-on products. It's a very simple technique but if you don't know about it you can find yourself FIGHTING YOURSELF trying to apply any spray-on liquid and the reason why is because when using a DRY microfiber towel to spread out a WET liquid, at the same time you're trying to spread the product out the DRY microfiber towel is trying to absorb and remove it. This is working against yourself and your goal of spreading a thin film over the surface.
So instead, try this...
Mike's Technique Tip
Start by DAMPENING one side of a folded microfiber towel with the product you're applying. This way the side you're going to apply the sealant with is already dampened with the product. If you don't do this, then trying to SPREAD out a liquid, (the SiO2 Spray Sealant), with a clean dry microfiber towel is a tick more difficult because the same time you're trying to spread out the liquid - the DRY microfiber towel is trying to remove it via absorption. So start by dampening one side of a folded microfiber towel and then use this SAME side to apply and spread out the SiO2 Spray Sealant over all the painted body panels. I'm fairly confident you'll find this technique works so much better than trying to spread out a liquid with a dry towel.
Directions
Now with the technique explained, here's how to apply and remove this product
Step 1: Spray some of the SiO2 Spray Sealant onto a section of paint.
Step 2: Using your towel dampened with the SiO2 Spray Sealant, gently spread the sealant over the section to be treated.
Step 3: Switch to your second, clean DRY microfiber towels and buff that section to a dry, high shine.
When moving onto a new section of paint, overlap j
ust a little into the previous section for uniform coverage. Repeat this process until you have applied and wiped-off the sealant to all the car's body panels. Now let's walk through the above process with pictures starting with my technique for using spray-on sealants...
First, using my technique shared above, dampen one side of a clean, microfiber towel folded 4-ways.
This side is now damp with the SiO2 Spray Sealant
Here's another technique tip - grab the EDGES of your microfiber towel by CLAMPING them between your thumb on one side...
And your index finger on the other side like you see here. Then pull up the edge a little and spread the rest of your hand and fingers out over the back of the towel. By doing this you're able to firmly grip your towel while maximizing your handprint while wiping.
Step 1: Spray some of the SiO2 Spray Sealant onto a section of paint.
Step 2: Using your towel dampened with the SiO2 Spray Sealant, gently spread the sealant over the section to be treated.
The goal is to gently spread-out a uniform film of the SiO2 Spray Sealant
Step 3: Switch to your second, clean DRY microfiber towels and buff that section to a dry, high shine.
IF you can make black paint look great you can make any color of paint look great!
