Re: 3m 5200 adhesive/zinc anode

Now i 'm not trying to burst a bubble,I use the acid cleaner then you said rinse with water,does that mean i don't have to put acetone on it at all before i go with the epoxy?Also i wanted to ask,whats better because i have both,marine tex rapid set or the reg jb weld?I should have this all under control after these last questions.Thanks to everyone for the help

Re: 3m 5200 adhesive/zinc anode

You can use the acetone before you grind out the pits and just use the acid after grinding....the acetone will remove contaminates so you dont push them down into the surface while grinding. The acid etches the aluminum, so to speak, and the water removes residuals before the bond.

I suppose you could use MT or even Gluvit...i just like the jb.

Ok i'm going to give this a go tom morning.I don't have a drill attatchment wire brush,but i do have small wire brushes i can use if that will work,i have everything else.

You should be ok doing it by hand, just make sure you get all the white oxidation off, you want clean white metal in the pits.



what are you planing to cover it all with? if paint, there are a few steps needed for proper adhesion ....if so.....just ask

Have Fun!

Re: 3m 5200 adhesive/zinc anode

Funny you ask, i was going to paint it but here in fl it's getting cool if you want to call it that,lol.It's big seatrout time and i'm so over ready to fish it's not even funny.We have what we call a massive cold front coming next week and after the cold settles in it's go time for the fish.I was going to paint it now but i'm going to just wait till summer if the pitt area with the jb weld holds up or i'm just going to sell this boat and get a new one.I had an aluminum boat from new like this like ten yrs ago and never have seen this pitting before,when i sold the boat(biggest mistake)it was like new.I guess because i took care of it,it lasted with no issues ever.Thanks for all the help and i will post before and after pics.

Here it is now from what i sanded so far from the first 5 pics you see,i just took these pics now.

Re: 3m 5200 adhesive/zinc anode

I just have one question,if i decide to just leave it alone and do nothing but fish with it,(now rem it's trailered and will never sit in the water longer then i fish with it)will it make it through till summer without getting much worse?I just want to fish now and do this later in the late spring to summer.I rinse the boat down everytime after use,flush my outboard and soak my trailer down.

I just want to make it through the fall,winter and spring,so say 6mths or so.I checked how thick my aluminum by looking in the screw hole i have to seal and it doesn't seem to be anywere near going through the bottom,i mean not even close.Thanks for any input.

Re: 3m 5200 adhesive/zinc anode

Dude..... Dont leave it like that...now that you got it cleaned up just spread some JB weld on it.....the crap hardens in about 5 min sand down a bit and go fishing.

Re: 3m 5200 adhesive/zinc anode

hit is with a wire brush, jb weld it, then a coat of either gluvit or even rustoleum with hardner

Re: 3m 5200 adhesive/zinc anode

I have decided to do it the way most people are saying,I'm not going to worry about it right now,my new bunks are not going over the top of the pits they are going to the farthest outside part of the boat over the factory paint that it still has on it.I have been asured it wont do much more to anymore damage in only 6-8mths because i'm trailering in and out.I'm just as of now going to take my little girl fishing before it gets so darn hot again here in fl.I am going to make a decision in late spring whether i'm going to keep it or sell it.Till then i don't see how anything will happen to it especially when the pits are not that deep.

I will print out and follow what directions you guys gave me if i decide to keep it which i probally will.I just want to fish now,thank you guys for helping me and i will put after pics when i decide to do it.

Re: 3m 5200 adhesive/zinc anode

Ok one last post.....Im not following your thinking, the bunk rubbing on that spot has nothing to do with the damage - pitted area.
So there is nothing in the water that you can hit, scrape, poke holes in the weak/damage pitted area! Thats what i would be worried about.......especially taking my family member out fishing.

Just me and only me......but i would take a few hrs from my fishing time to fix it.

Good luck and make sure you have your PFD's aboard!

Re: 3m 5200 adhesive/zinc anode

At the very least, I'd primer it, and paint it to seal it from the saltwater corrosion. $20 bucks of prevention with some Rustoleum.!!

Re: 3m 5200 adhesive/zinc anode

The pitting is not that bad,i thought it was and i'm not so worried about it that much anymore.I went to tinboats to get some info also and there is a guy who has been running aluminum boats for over 40yrs and has had this issue about 30 times with used boats he picked up,i asked him how long it would last like this and what damage it would do in 6-8mths.He asured me that little to no worse damage would happen if constantly trailered in and out of the water and washed down good after every use.

He totally agreed with what steps you all said to do as fas as fixing it but said don't worry about it and just go fishing and fix it in the summer if thats what you want to do.I saw one of his boats he posted for me and i thought mine was bad,the one he's fixing now makes mine look new.I think someone with over 40yrs experience would know what there talkin about so i trust his judgement.

He said you want to make sure you fix it 100%right though in the summer if you want to keep it.

Acetone first,then wire brush all the pits till there is no white powder left and is 100% clean,then wash down,then use the phosphoric acid as zool said,wash down again,then acetone one more time after that,let it dry and then jb weld it,sand it,go with gluv it,then paint over it and done,that should last forever he said as most of you say.After learning about this and how common it is on aluminum boats i'm not as worried as i was before,i just want to fish through the fall to spring and then i will fix the issue.

I have never seen this on any boat i have ever had so it freaked me out.I have always had new boats and that has never happened to any aluminum boat i have ever owned so i didn't really know how bad it was.

Woodonglass i get what your saying but i'm not going to half a#$ it by just throwing primer and paint on it just to strip it down in 6mths again,you know what i'm saying?I'm going to do it all out right in 6 to 8mths or i just won't keep the boat.If i do this i believe in doing 100% right and by then i will have all the time i need on my hands,right now i don't and i'm ready to fish for now.Thanks to everyone on how to repair it,when done i will post pics of before and after.

Re: 3m 5200 adhesive/zinc anode

Well then at least post some pics of the fish you catch

Re: 3m 5200 adhesive/zinc anode

Putting primer and paint on it now, would not, IMHO, be Half *****ing it. It would be doing the right thing by preventing further corrosion until you do it "The Right Way" Stripping the paint off will be an easy process when the time comes. Your boat...Your choice. I'm just sayin I'd never put an unprotected aluminum boat in saltwater based on what I've learned about the corrosive action that occurs. Especially when $20 bucks would stop it.

 

[boater1234]

Re: 3m 5200 adhesive/zinc anode

I understand what your saying but if it won't get any worse in 6-8mths what is the big deal,i'm not going to prime and paint and then in 6mths strip it and prime and paint again,that makes no sense.There is tons of boats i have seens that are left unpainted in saltwater.If it's trailered how can it get any corrosion on it when it's washed down everytime with freshwater?I have owned tons of aluminum boats and believe me the paint on the boats are cheap paint and it flakes off like nothing especially on the bottom and in the many yrs i have owned them i have never had pitting of any kind whatsoever.

I can understand if it's left constantly in the water it will do damage.Thats not what i do though.I'm going to do it all right in 6mths and then i will post pics after it's done.Even my local marina i have gone to for 15+yrs who sells aluminum boats said very,very little to no damage would happen in 6-8mths,go fish with it then worry about it on the off season.So that is what i'm going to do.

Re: 3m 5200 adhesive/zinc anode

Well then at least post some pics of the fish you catch

100% i will,some monster trout,reds and snook,then some fat sheephead in jan and feb,yummy.

Re: 3m 5200 adhesive/zinc anode

Boater you sure stir up a wake in that little Jon Boat of yours!

Re: 3m 5200 adhesive/zinc anode

Pease accept my Apology!

DUH!!! I've REALLY got to read and understand better. Of Course if you TRAILER the boat and WASH her down each time you'll be golden!!!! Like I've said many times before, I AM just an..

 

[boater1234]

Re: 3m 5200 adhesive/zinc anode

I'm thankful for all the info you guys are giving me.I'm not trying to stir up a wake.I just want to do the whole boat right at one time thats all and i have very little time to fish here in fl for big trout.I'm talking monster trout,i know trout are easily caught all yr around but not like they are now through like march/april.

I'm sorry if people here think i'm trying to start a wake,i apologize for that.I am going to take every bit of info everyone here has given me and use it.I have decided to do it the way everyone said and add the gluv it on top of all that to make it a permanent fix.From what i gather you can leave it unpainted or paint it, i may as well paint it with a good epoxy paint after i get the gluv it on and i should be set for a long while from what i've read.

Thanks to everyone who has helped me,it means alot.
