I have been using plastic wood to fill in the weight holes in my jointed swimbaits. It seems to leave voids after it dries. What have you guys been using for this?

I was using CA glue mixed with micro balloons, but my new brand of CA glue dries too quick to allow this. Now I am using bondo filler.

I'm getting ready to try water putty. I have some that I had to fill holes in my plaster wall. It will soften if water gets to it, but so will the paint so I figure I'd give it a shot. I'll let you know how it goes.

Once it is cured and shaped, coat it with CA glue. This will strengthen and water proof it. Just my thoughts.

I use water based wood filler or spackling. Exterior wood filler on hardwood baits and interior/exterior spackling on balsa baits. Both dry quickly and are easy to sand. I don't want a filler that is harder than the wood around it because it's hard to sand smooth without damaging the softer wood around it. I undercoat baits with epoxy afterwards so whether it is waterproof or not is not an issue. I install integrated belly hangers/ballast weights with epoxy putty, which you can smooth out for a neat appearance in the couple of minutes you have before the putty gets hard.

I use all of the above and the easiest waterproof solution i have found is epoxy putty. I need it to be water proof because I test my baits right out of the mold and use different weights. I dont have to seal them if I use the epoxy putty. Just knead it stuff into whatever void u have and wait about 10 mins...It also sands very easily.

i have been using loctite repair putty. its sands easy when you let it dry for a few min and it has really strong hold if you want it is strong enough to hold your screw eyes if you use them. http://www.loctitepr...lti-Purpose.htm

Okay, you guys sold me on the bondo. I bought a bunch of that magic putty on sale and was using it. It works great too, but the bondo sounds just as good and easier to find now.

I too like bondo. Its a little bit of a pain only because you have to mix the hardener...but its also a benefit because if you add enough hardener to make the mix a dark pink you will have something that dries very fast over even wide deep gaps and holds. I used to have the same issue with having to sand so aggressively that I would score the area around it. (Which is still fixable of course). What I like to do now is let the bondo setup pretty well but not get too hard and then hit it with some 60 grit and it is real easy to sand off the excess without much effort. So far I haven't found anything that holds as well on my test baits that I don't even finish when testing. (Urethane).
Oh yeah, get some extra hardener (they sell it seperately), as you will probably go through it pretty fast as everyone I know ups the ratio of hardener quite a bit to get the quick dry times.

I also use bondo, and also go through the hardner faster than the putty.
Just remember that the more hardener you add, the weaker the bondo gets, so be a little patient, use a little less hardner, pink like JK said instead of red, and you'll get a better result.

I find the paste hardener provided with the bondo filler a real pain to work with. I always seem to use too much and the squeeze tube never lasts the course. Now I use the hardener that comes with the polyester resin, as I always seem to have plenty left over with the resin. This tends to thin the filler a tad, but it works for me.
I stand in front of my extractor fan and sand down using a drum sander attachment on the dremel (the hardener, MEK, is nasty stuff and you do not want to breathe this dust). Even though the drum sander is capable of removing a lot of material very quickly, I find that I can control the sanding process very finely, as you can get up close to eyeball the progress (don't forget eye protection). I finish off with 120 grit under my thumb and a coat of CA glue. I can usually get an invisible fill with this method.

Are you referring to auto body filler......if so what is a good product......thanks
Posted 17 May 2011 - 04:56 PM
Yes, it is used as an auto body filler. Bondo is a brand name and they sell other items under the same name, but the filler is generally called Bondo. I use a brand called San polac which is available locally for me. It is all the same stuff, polyester resin filler. I buy it by the kilogram tin and pay about $8.

In the states you ask for BONDO in any store it means only one thing.

I forgot to post about the Water Putty. It worked great. It's water based as I said before so it is pretty easy to work with. Just mixed in water until i got the consistency I wanted and then slapped it in the spots I needed it. I wasn't worried about it being water based. I was just stating that because I know that some people do. I have enough sealer on a bait to get a nice smooth paint coat that I doubt water will ever get to it. The thing about things being waterproof is kinda a moot point with me. I understand it and I don't want to use things on a topcoat or something that isn't waterproof, but how often do we really use the same bait for 12 hours in a day over and over again. We all know on days when this does happen it is so good that no clear coat would stand up to the fish we would be catching. I long for those days.

A better wood filler???
I've started collecting the sawdust from the CNC machine and mixing into a Medium Viscosity CA like Bob Smiths INSTA-CURE+. It seems to be odor free and dry harder and faster than bondo with good sanding results. They also sell two very thick CA's for big gaps and an accelerator. Anyone ever tried these?
Posted 07 December 2011 - 07:34 PM
When CA first became available, there was no medium viscosity option. I used to use microballs as a filler, and add a drop of the CA over them to harden them. That was probably 30+ years ago, and, if I remember right, the filler was really hard and brittle.
I use the gap filling ZAP CA and their accelerator all the time. It works great, and the accelerator lets me work as fast as I want to.
