3MPlatinum Plus Filler 01131, Lightweight, Stain Free, Tack Free, Quick Application, 1 gallon

Really good I have used this professionally and never had a problem. Easy to work with. Durability is great.

I use this primary on fiberglass and occasionally Aluminum, super strong easy to sand and tackless. Does peel from Aluminum like Bondo does.

This was my second gallon of this stuff. It works great. It does clog the finer grits of sandpaper but what filler doesn’t. This is very fine and creamy and will be useful as a glazing compound so you’ll save a few bucks not buying that. I would like to see a little more of the catalyst included as I’m running out of it before the gallon is used up. It’s price it less than the local stores and free shipping means it’s on the doorstep without driving.

This filler is GREAT! Fast drying, hard as a rock!

It's easy to apply, dries fast, and sands down perfectly. No mess, no stains, and it’s lightweight.

PROS:This works very well. It spreads easily, and dries fast, then sands easily. Minimal pin holes, if any.CONS:Comes in 1 gallon can that is only 3/4 full. I went through 4 cans so far that has added up in price, which would actually only be 3 full cans for the price of 4. Product starts to harden within 3-4 minutes, not 8 minutes, as suggested in directions. Product shrinks pretty significantly as it hardens, making a lot of work in building up even small low spots. Must sand between coats, or it will peel off the under layer.

This stuff is awesome! I investigated how to sand normal "bondo" (the pink stuff) since it kept clogging up my sand paper. Plus it would take forever to dry in the cold. Most people suggested this 3M filler over the normal Bondo brand.I couldn't be happier! OMG! Its twice as expensive as normal "bondo" but it applies like a thick cream and lays down without normally any bubbles. It sands like a dream and I find myself using the same sandpaper for a really long time without it clogging up. The longer that you leave this to harden the easier it sands. Plus it cures even in temperatures around 35F which I have unfortunately been working in lately trying to finish a project.Also, having repainted other cars and seen professional work I know for a fact that this stuff is what pro shops use. So it has a lot of durability and trust by the pros who repair cars.Anyways, I couldn't be happier and in the future when I run out of filler from this can I will be buying more. Its totally worth it to me for sandability, cureability, and durability.

Do yourself a favor and get this filler. Absolutely boss sauce. Quick, easy.
