3M Marine Premium Filler, 46005 1 qt , White

This filler is very durable, easy to work with, and sands easily

Recently purchased a quart of this product knowing I was gonna have a large glass project to fair in during a haul out on my hull above waterline and wanted to give something new a shot, and being a work boat theres never enough time or money to mess around with one project, especially cosmetically. after two rounds of fairing and a couple coats of high build epoxy primer a 4'x4' glass repair was ready for paint, strong,sanded well. Have already suggested it to other fisherman for glass fairing. My only complaint is I cant find it again!!!

Easy to use for a first timer. Product works great!

Used it to fill gouges on used 25 foot boat I bought an some small fills.. Set time is really fast, make sure your ready and preped prior to mixture. Worked really good, went over a small area a second time due to some small pitting which wasn't even an issue. Just sprayed on gel coat came out really nice no shrinkage.

Used to repair gouges in keel. Applied simply enough. Was able to sand in15 as advertised. As everyone else has stated work fast and in small areas. I mixed up filler with putty knife and used small scoop with a pea size dab of filler. Clean tools with acetoneI am not sure about using without top coat of some sort. I am using gelcoat

It is far superior to most polyester putties. Easy to sand unless you wait a day or two. Sands smooth and bonds well.

Recommend!

Great product, dries fast and Strong! Great product for filling holes gouges chips and even crazing cracks fills in everything on your boat! Just buy it
