How can I speed up curing of the HL Sealer?
Cure time is effected by climate temperature and humdiity. Higher temperatures and low humidity will give faster cure times.
Heat sources will speed curing. Turning on headlight, household hair dryer or heat gun can work. Care must be taken if using heat gun or other high heat sources as over heating can damage lens. Only use if you are confident that you will avoid damaging areas recieving heat.
After heating for a couple of minutes allow to cool before checking for tackiness. HL Sealer will still need some time after heating and cooling to get a surface dry.
The All new HL Lens Coat
HL Lens Coat is an air cure coating with a heat accelerating feature (HAF). If you need a faster cure take advantage of the HAF by applying a heat source. Any heat source such as summer sun, headlight high beams, hair dryer or heat gun will speed curing. Care should be taken when using an external heat source so as not to damage lens or surrounding parts.
Allow to cool for 2-3 minutes. When a lens is not sticky to the touch it is safe to drive.
NOTE: After the initial surface cure their is a full cure period. Allow 30 days before washing or waxing.
Should I always start with 400 grit?
You can, but it really is not always necessary. It all depends on the severity of damage. Until you get more familiar with the varying degrees of damage you could test one spot on the lens and decide if that grit will quickly strip off the corrosion.
For Example: You examine a lens an believe it is not too severe but does have some pitting so you sand just one spot with 1000 grit. After you cleaned off the spot, you notice some of the corrosion did come off however the tiny pits are worse than you thought. So decide to sand the lens with 600 instead or even 400 if it’s that bad. You want to remove the corrosion as quickly as possible on the first step. However with lighter damage you can start with a finer grit and avoid unnecessary sanding steps.
I assume wearing protective gloves is a good idea; do you suggest technicians where gloves?
Yes. The chemicals will not immediately harm skin, however as with any paint related material gloves provide protection against long term effects.
Is there a guarantee on this product, it works really well I just wonder what to tell my customers when they ask “How long will it last?”?
Different types of coatings attract and hold dust particles differently due to static attraction and how viscid it is. Other spray on coatings can allow particles to be trapped under the coating.
Our coating does very well not attracting air borne particles. One of our customers in Arizona said: In the event there is dust on lense, it can easily be removed by lightly rubbing some car wax over surface.(After lens has cured).
This is of course due to our coating being a wipe-on formula, which allows any particles to be only on the surface.

Why did my HL Sealer/HL Coat dry milky?
Water or moister is your cause. The most common reason for this is hidden water around edges or under side of lens. The water is picked up in the towel during application. Thoroughly dry edges before applying HL Coat will solve the problem.
Why did my HL Sealer/HL Coat dry streaky or with lines?
There are four reasons why Clear Wipe will dry this way.
1. Hidden compound from polishing.
2. Applying to thin.
3. Excessive wiping.
4. HL Coat has thickened in container.
Below are more details on the 4 reasons:
1. Left over compound hidden application. This will usually begin to show as HL Coat dries and look like gritty streaks.
2. HL Coat should be applied generously. After wiping edges with corner of towel apply into HL Coat before proceeding down lens. The lens should be very wet with HL Coat.
3. HL Coat should be applied quickly and generously, areas or runs. Once it is applied it begins to dry so once applied discontinue wiping and allow time for it to level. Cooler weather will give plenty of time for HL Coat to be applied. As weather warms there is less time to apply.
4. HL Coat may accept small amounts of mineral spirits if it has not to far gone. The most common cause of thickening is untightened caps. For the best seal tightend thoroughly then rap bottom of cap tith electrical or teflon tape. Near freezing or below temperature will cause thickening. This is not due to solvent evaporation so thinning should not be done. Storing containers in warmer locations will relieve thickening.
