West System Pumps.

Is there any way to store and reuse the West System pumps? I've been using hardware store 'marine grade' epoxy for some time. I'm thinking of taking some advice from SN and getting some West stuff, just thinking about storage and making the most of the purchase.
Had trouble posting my profile pic, a 73' San Juan 21. Will get there.

Sure. Ive had the same pumps for several years. I normally leave them in the cans and they work fine like that up to a point. After more than a year, I have had the epoxy crystallize in the pump. But by pulling (they still sort of worked) solvent (I believe acetone, maybe lacquer thinner, check West for proper solvent) into the pump and letting it sit overnight, then pumping some fresh solvent in until clean, they were back to good as new. Just remember they are calibrated for West epoxy and may not be right for other brands.

I agree fully with scosch having had the same experience for several years. Pumps continue to work great.

i go against normal beliefs here, i have had too many pumps that did not work right, always the hardener pump. i use measured cups, the normal ones you see everywhere. it is easy enough to add 5 ozs resin, then one oz hardener, then mix real well pour out of cup in to something that will allow the resin to spread out more like a pie pan. the reason i use the pie pan is if you leave the resin in the cup and its a tall column it can heat it self up and start setting faster.

use the pumps but check the calibration by using the measured cups, then pour out in to a thinner layer after mixing

In the hardware store epoxys its always the hardener that won't dose properly. Funny that scottyt have that isssue.

Looks like i can buy a decent amount of West System and it'll hold. I just pictured the pumps would freeze between lay-ups. Sounds like they go for years.

I learned a clever trick from the folks at MAS epoxy. When the pump stops working, dunk (not submerge) the container in hot water. It may take a couple of water changes for the heat to permeate the container, but once warmed up, it softens the whole works and voila, the pump works like a champ again.

PS, I'm using MAS F.L.A.G. epoxy because it doesn't need to be thickened for use as glue. I've only had to use the hot water trick once. I've never had it happen with WEST epoxy which is much thinner.

looks like MAS is a little more pricey, but it you don't have to buy thickener for West... so when would i use epoxy as an adhesive, rather than 5200? Any pros, cons?

5200 is not a replacement for epoxy, and IMHO shouldn't even be used on a boat. 5200 has too strong an adhesion strength for anything that may need to be removed at some point in the future, and you should probably be using 4200 instead.

Epoxy is really a structural material, and should be used to do things like attach stringers to the hull, fill small voids or holes, etc. However, epoxy has one major caveat to it. It must be painted or coated to protect it from UV degradation. Epoxy breaks down under UV...

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

I have had numerous pumps over the last couple years. they always seem to keep pumping, however over time i always seem to break the plastic collar of the pump when it gets knocked around. Even then they still seem to work. If you are planning on doing smaller batches i would suggest another method (mixing cups or scale) as there always seems to be so much waste with the pumps on smaller jobs

I've had good service from the pumps as well.

My preference is for a no/low-blush epoxy like M.A.S. or System Three.
