3M Marine High Strength Repair Filler
 
Does anyone have any experience/feedback using 3M Marine High Strength Repair Filler? It's a vinyl ester compound. I'm interested in using it for minor deck repairs ... some screw/through-bolt holes from removed hardware and and two openings, the largest being about 5" x 3". I want to fill and fair. Will paint the deck next season.

I have used system three silver tip quick fair filler Underwater for keel fairing and on deck for fairing dings and holes I have closed up

It mixes very easy and sands very easy And has held up for three years so far

I haven't used it but every 3M product I've ever used has been the best of whatever it was. I would use that filler in a heartbeat.

It's a great company.

Yeah I pretty much second this. 3m makes a lot of great products. I'm really fond of their VHB structural 2 sided tape. Although I've probably used it in a few too many places.

That said it's also impossible to go wrong with west system epoxy which will also do the deck fill jobs you're talking about and a lot more. It's expensive to initially buy the 105, 205, filler, pumps, syringe etc but once you've got it you can do everything and epoxy is pretty much the best for all these types of jobs.

While I am also a 3M fan, I'm more an epoxy fan, especially below the waterline.

A nice epoxy mix with some 407 or 410 filler mixed to the needs of each particular job is as maleable as you need it for each such job, and sands wonderfully. The 410 is awfully light though, only for cosmetic repairs. 407 is someplace between cosmetic and structural.

Yes, 3M makes good products, but I can't see filling a 3 inch by 5 inch hole without using some glass if you expect there to be any strength. I once upon a time filled holes about that size with bondo on a fender and it did not last long! Perhaps a screw hole, but not a big opening like 3X5. I think one good kick and it will pop out or at least crack.

I used fiberglass resin with colloidal silica to thicken for filling bolt holes. I agree with miatapaul about using glass and resin for structure and strength in any larger areas.

Oh I agree. I missed that. Speaking of 3m Home Depot sells 3M glass cloth. $7 for 9ft sq. I'm not sure how that stacks up to marine prices but I'm guessing its less (for that small a size anyways).

Yes, Lowes sells 3M fiberglass resin and hardener and fiberglass cloth for quite a bit less than the marine sources.

Of course, it cannot possibly be as good as "marine" epoxy, hardener, and cloth, because it is half the price and does not have a picture of a boat on the label...;) (Plus, no one is making seemingly objective claims of incredibly superior tensile strength based on their own in-house testing.)

If they sold epoxy resin that would be news to me. I thought they had 3m polyester resin. Not that that's bad but epoxy is a notch better.
