Thread: Tape for small hole in alloy hull

Is there anything you can use to plug up few small oxidation holes in alloy boat hull?thinking an underwater tape instead of silicon product,have had holes welded up in the past but hardly using the old girl these days,only lake and harbour fishing with the kids so nothing to extreme..no bar crossings or beach launching.cheers

get a fi-glass repair kit, rough up the alloy and go to town

Drill and pop rivet?

Pop rivet would be first choice. But I have used "Marine Weld" It is an epoxy made for alloy oxidation. Made by " J-B Weld " Great stuff highly recommended.

+1 for Jb Steel Stick, works primo and handy as you cut off and knead only what you require and keep the rest until required- lasts for ages, just wear gloves and give the area a good coarse sand so it’s got a good key.
Cheers ��

Think I have some of that stick weld stuff somewhere in the garage too,

They cut this boat in half & used Flex Tape to hold it together.

It was on TV so it must be true.

naaah. no suzanne paul in the ad

Yes I have used "Flex Tape " before as well, great stuff.

I used a flashing tape used for roofing that i found in the shed - my dad was a builder and left a roll of this tape that had a metal foil with a bituminous production on one side - i stuck on the inside of the hull over some pin holes in the alloy and it stuck well and stopped the leaks. Lasted well too

Windscreen sealant. Ms1 both awesome.

The tape to use is eternabond. Designed for this exact use. You can get it in white, black or aluminum. It’s not super cheap ( $119 for a 50mm x 15m roll) but incredible tape. RV centers have it.

JB weld. have some on an alloy radiator on my dirt bike, and on a crack in the crankcase. Been holding pressurised hot water and hot oil back for 6 years now

Your local boot repair man will have a tube of Shoogoo that will fix those small holes. Its black and sticky and sets flexible .
