3M 5200, interesting stuff...

[D. Stump, Hanalei]

Because it's cold in New England, I've been spending my time building a new 8' pram for Hanalei by the woodstove in the basement. I'm using 3m 5200 adhesive sealant to join all the panels and framework. The problem arises when one trys to remove the sealant that squeezes out when you tighten down the panels. Someone said on this board that 3M made a solvent for the stuff, but I found that another readily available solvent works great, and it's cheap. I got some of the stuff on my cheek the other day, close to my left eye. Just trying, I picked up a bottle of Isopropol Alcohol from the medicine cabinet, and Wah La!!!, it took it off very easily! The stuff I used was 90%, but I would imagine any isopropol alcohol would work. Try it, it works, it doesn't say MARINE on it and it doesn't have the MARINE price tag. Oh, I tried it on the joints, even ones that had been exposed for a few days, and it took the excess right off. 3M's going to hate me, huh?

Dave,

Thanks for the info! I'm the guy who told you about the solvent and I AM VERY GLAD to learn about the non-marine alternative!! If it says marine, aviation, medical, dental, professional or the like the price ALWAYS goes UP, UP, UP!!

How is the boat coming? You will have to post pictures on the Board for us to enjoy when you are finished.

Thanks for the info!

Lyn,

It's coming out very well, thank you. Actually, it's about the sixth time I've built it. Started about 20 years ago, from some plans I got from the American Plywood Association, and it makes into an ideal little dink for a sailboat. She will tow behind, riding balanced on the quarter wave, is very lite (80#s), and never causes any excess drag or trouble like an inflatable would. One thing that made this one come out better than the five I've built before is that I had the old one in the back yard to take the angles off of. That resulted in the planking meeting almost exactly with the framing. The resultant joints, sealed with the 5200 are almost perfect.

Don't know if I'm sharp enough with this computer to scan a picture, but if I can figure it out I'll post a picture of her when finished. The isopropol did work just great!

Dave,

So glad to hear it is going so well!!! I have been trying to decide on a tender for MOON CHILD. I have used "hard dinghys" with GUILLEMOT and was quite pleased with them, but there is the tease of the inflatables and their "softer" gunnels, etc. There must be something right about your tender as you have built so many!!

Waiting for the pix!!

Thanks so much!!!

Warmly,
