The problem with using large bags and large
batches is that the pot life of epoxy and adhesives is directly related to the size of the batch. ------------------------------------------------ I think you'll find it's easier to put a small batch into a large bag than the other way 'round :-) I've found it best to assume everyone knows at least as much as I do about engines, planes and who shot John. Steaming under those rules, if someone shows signs of not having used a particular tool or technique, the mere mention of it should be enough for them to determine if it can be applied to their particular need. That is, after leading the horse to water the rest of the job is up to the horse :-) -R.S.Hoover |

ain't picked no cotton with Earl, but I bet it's neoprene lined-not teflon--"taint near as good.--no cure date on teflon--indefinite shelf life. "Bart D.

No soft stuff for me. Same goes for the brake lines, SS not nylaflow. Thanks -- Bart D.

Same idea as for decorating a cake but on an industrial scale; used for accurately placing/dispensing mortor, filled epoxies, high-viscosity urethanes, etc. I believe you'll find the weak link in using caulk-gun tubes is filling the things. With ziploc's and baker's bags you can do the mixing IN THE BAG, be ready to place even fast-cure compounds as soon as the mix is uniform. Or? Lay the mixed bags in the refrigerator while you mix some more. (Never used a baker's bag? Squeeze out all the air, hold it closed, give it an easy spin... not too tight... then snip the corner according the size/shape of bead you want to place. With a gallon-sized ziploc you can place about one quart of mix; baker's bag can handle up to a full gallon. SOP for your application, or applying 2-part sealant for riveted aluminum fuel tanks, pontoon repairs, etc.) -R.S.Hoover |

You may have to hunt to find 'em, but they _are_ avaialable. |

Old thread, but I just bought some here...
http://www.multitechproducts.com/pro...h-Plunger.html They worked out great, glad I found out about these. I always just assumed you had to buy ones that were already filled. |
