FishyFish Tolman Alaskan Skiff and Boat Building Forums

I bought a tube of dap caulking (plastic tube). Dispensed the dap into the garbage, cleaned the tube (use a 1/4" dowel to push the plunger back out the back).

Used the tube today full of epoxy/microfibers to apply a glue strip to the bottom of the stringers.
The caulking tube worked great, I plan to use the caulking tube again for putting beads of fillets in.

Cleaned the tube with alittle acetone and it's ready for use again.  It appears to work great.
Just put a bolt in the end to plug the hole and fill with your favorite epoxy glue.

everything I found was around $2, Dap caulk at Bi-mart was less than $3.  Does not pay to order some and pay shipping.

I think I can get buy with buying 3-6 for the whole boat, they clean up with acetone just fine.

I've never used a piping bag, or similar (except for actually frosting a cake), so have no experience (with epoxy) to speak from. But thinking it through in my head, it seems like in the time I would spend troweling my epoxy mix out of the mixing container and into the dispensing bag/tube, I could have just troweled said epoxy mix directly into the joint I intend to fillet (which is what I did on my build)...no?  Is there really that much more efficiency to be gained there that it's worth interjecting another container/dispenser into the process?  Help me understand what I'm missing. Let's say you mix up some epoxy; trowel it out of the mixing container and into a bag; then apply it into a corner joint; then you smooth the mix into a fillet with your knife...and then what are you doing with the little bit of excess squeeze out/overflow that occurs around the edges of the knife? are you picking that up with you knife, and putting it somewhere (i.e. back into your mixing container), or?

Yes I agree it just another bit added to the process.

Problem I always had was getting a good even bead in with my rounded putty knife, always dropping the good stuff
and generally making a mess and having to reload and trowel it into the joint. I did the sandwich bag thing and that worked fine and for me the frosting bags were just an improvement of the process. I set up the bag in an empty QT container and scoop my epoxy mix in with my mixing stick, work it down, snip of the end whatever opening I like and lay in a nice even bead, work it with my rounded putty knife, pick up the excess to use filling holes left from screws.

sometimes will lay the tape into the bead with out working with a rounded tool first. Just lay it in and smooth it to the contour.

Very little is left in the bag as I smooth towards the end as I go.
