Q: null Roughly amounts of 404 filler to mix with resin to get just thick enough to not sag on vertical surface vs thickest useable mixture .

A: I just start mixing a bit in at a time until I get the consistency I'm looking for. As you gain experience you get a pretty good feel for how much to add at a time. Too much at once makes it kind of hard to mix well. I also prefer using the slow hardener. I found trying to make a thick mixture can set off the fast hardener before I'm ready, also less stressful. I also combine fillers depending on what I'm doing. I've found using small plastic (medicine) cups, like from a NyQuil bottle, or other small container. I scoop out a small container full to work from so I can keep the large container closed to avoid moisture getting in. I also use rubber mixing bowls like you see in a dentist or orthodontist office. My dentist ordered me a couple different sizes. They make mixing much easier as there no sharp inside corners. I reuse them by wiping out residual epoxy and cleaning them with a little alcohol. With the amount of work I've done I figure this has saved me a significant amount of money compared to disposables and provides much better mixing.

Q: null I need to adjust the angle of the propeller shaft strut. The mounting surface is not flat and has some voids that using a whim would leave gaps. Would product be sutible with the proper epoxy for such a repair?

A: If you are using it with epoxy to fill in the area, then bolting the strut, that would be fine.

Q: null I need to fill hardware fastening holes in my boat deck. Is 404 the correct product?
8 years ago2 Answers
A: Generally 404 is a good choice for filling, but if extensive sanding is required a better choice might be 407 or 410 (see related questions and answers). I usually have 404 and 405 available.

Q: null Do you consider this the best filler product to use for filleting seams, or do you recommend another filler West System provides? I'm most concerned with strength, not weight or color. I'm constructing a stitch and glue dory, with fiber tape on seams and fiber cloth over entire hull.

A: So far, this is the best that I have found. I am an amateur, but I have used the West fillers extensively, and I have yet to be disappointed. I have tried other systems, but none allow for the mixing of filler to obtain the perfect consistency. Strength has never been a problem. Good luck..hope this helps...johnpaul
