Colinite 915

915 looks great and is very durable but be careful when using it. First off wear gloves on the hand that will be applying it, via applicator or whatever because it does not wash off skin easily. Second be mindful of how hard it cures if you apply to thick, it will take some muscle to wipe off.

For me I used it on my car only 1 time because I found that even after many wipedowns it left some smearing, this is more likely to occur on a non metallic finish (my car is)

If your working on a car that has a soft clear or is very finicky, 915 may not be the best choice to use. A polymer sealant may be a better route because of how easily they buff off.

Also after it's buffed off and cured go back and do a wipedown or 2 with distiller water.

And wash your applicator immediately after use sonit does not harden and you can use it again.
 
Layering 915 will give you smearing that you'll see on darker paint quite easily. Like already said a wipe down with ice cold distilled water between layers will help. The use a QD when your done. 3 layers was difficult remove all the smearing. I stick to 2 layers when using 915.

Skip the QD it could just as easily add to smearing problem. I won't QD a fresh waxed car inside of 24hrs.

+1 except for the 2 layers, i don't use it often anymore now but back then i didn't layer 915 since got no luck in smearing problem (can't be seen under the sun since my car is metallic but can be spotted using luxeon led) but for my condition 1 layer was pretty durable (till the time i buff the car again).
