Recommended Posts

alluiminum boat splashwell needs re sealing, Should I use adhesive type product? Needs to be oil and solvent (gas) compatible. Any recommendation? Removed old caulk and cleaned up with paint thinner.

Tony, I have had good luck using BoatLife Life Caulk. Comes in clear and white. The stuff is bulletproof above and below the waterline.

Good luck

line guy,

You posted a hyperlink with a few hundred characters. That's exactly what malware and spyware looks like when spammers hit this site. My post was meant as a word of caution to others, nothing more. Now that you have actual photos posted, you'll get advice. Most boat owners use 5200.

 

3M™ Marine Adhesive Sealant 5200

For over five decades, 3M™ Marine Adhesive Sealant 5200 has been a trusted, industry standard-setting sealant across a wide range of boat maintenance and repair jobs. This tough and flexible polyurethane polymer adhesive and sealant forms permanent, waterproof bonds to wood, gelcoat, fiberglass and more. Excellent for use below the waterline, it is especially effective on through-hull fittings, transoms, bilge areas and other applications where leakage is not an option. Above the waterline 5200 is excellent for interior panel bonding and sealing. It applies without mixing, fills gaps and delivers long working times for precise application and performance. It resists vibration, swelling, shock and shrinkage to maintain a solid, uniform bond and seal.

Jd,  didn't know pics loaded that way, my apologies.looked normal on my computer. Now I know thank you. I think the 5200 maybe to much on the permanent side. Would like to be able to take apart if ever needed.  Kevin, I'll look at boat life. Thanks for all the feedback.

I found an old Boat US magazine article about boat sealants and adhesives. 

The best sealant in your case would be BoatLife, a polysulfide, or 3M 4000 UV, a polyether. 3M 4200 and 5200 are polyurethane construction adhesives and not chemical resistant.
