NEED HELP REAL BAD-Painting jon boat

[PIPER354]

I am new to this forum and this is my first post. I have read througha bunch of post about painting jon boats and have my own set of problems.

I have a 1999 Lowe 1448M jon boat with a 2001 Johnson 25h. for the past 7 years it has been a hardcore duck boat, but i decided to make it into a fishing rig. My 8 yr old daughter has recently started fishing with me.

My plan was to repaint the boat and get away from olive drab. I took everything out of the boat, took the engine off, put the boat on saw horses. cleaned and sanded the entire boat. The paint was in good shape, just some cosmetic scratches. Primed the entire boat in LATEX primer.....

I am now in the process of DE-PRIMING the entire boat. Boy did I screw up bad!

Have been using a power washer, oven cleaner, Xylol, and all kinds of stuff to get it off. It is working, but real slow. When I am done I plan on painting with Parker Bay Gray duck boat paint. I also want to prime with the correct primer.

Any suggestions on what I can do to make my life easier?

Also, I noticed that self etching primer will take off any existing paint that it touches. I have used Zinc Chromate on aircraft with bare aluminum, what does it do if it gets on a painted surface?

Thanks in advance!

Mike

Yeesh.

Well, you're in luck with latex primer there's all kinds of non-scary stuff for that. Have you tried any of the latex paint strippers? I'd go with the citrus-based stuff and save yourself some potential chemical poisoning.

Then, use a proper below-waterline aluminum primer like interlux primocon or the like.

Some might consider that over-kill, but I'm a do it once and forever kinda fella.

Re: NEED HELP REAL BAD-Painting jon boat

I am going to repaint my aluminum boat in a couple months and I talked to a guy at interlux paint. Heres what he said:

"Since the boat is not in the water for longer periods of time you can apply a topside coating on it like Brightsides. To apply remove all of the old coating on there now and bring it down to the bare metal. Wipe clean with 202 solvent and sand with 150-160 grit sandpaper, re-wipe with 202. Apply 1 coat of Vinylux Primewash 353/354 (etcher). Wait 1 hour minimum but no longer than 24 hours. Apply 3 coats of 404/414 Epoxy primekote. Sand lightly between coats with 220 grit and wipe clean with 333 solvent. Apply 2-3 coats of brightsides, again letting it dry and sand lightly between coats as you did with the 404/414."

Probably more than you want to do but if you di it right it should last a long time. I'm not sure what Xylol is but have you tried using some sort of paint stripper to get that latex stuff off?

Re: NEED HELP REAL BAD-Painting jon boat

Xylol is a laquor solvent, in the same sort of category as acetone, mineral spirits, etc. It's used a lot to remove varnish from furniture, and it's really nasty highly toxic stuff - lots of fun at parties.

But then, I never get invited to those sorts of parties.

Latex is one of those compounds that can't be dissolved by most of the solvents you'll find at the hardware store. I think acetone will work on it though.

Anyway, you're better off with a real non-toxic latex paint stripper.

Re: NEED HELP REAL BAD-Painting jon boat

I am trying to remove the latex without removing the original paint. I know I could easily strip ALL the stuff off down to bare alum, but I really do not want to do that. I only use my boat about twice a month and it is in the garage the rest of the time.

Will look into one of the non-toxic paint strippers. This has really ruined my life for the last 2 weeks.

Re: NEED HELP REAL BAD-Painting jon boat

If you're not removing the old paint you should just sand that w/ 120 and prime with an epoxy primer. You'll just make a gloppy mess using self-etching over old paint.

Re: NEED HELP REAL BAD-Painting jon boat

That is what I noticed about the self etching primer. I will get there, it will just be a lot of work. Thanks.

If I prime any bare areas with Zinc Chromate will it bubble up the adjacent painted areas?

Re: NEED HELP REAL BAD-Painting jon boat

It probably will, but at that point the aluminum underneath has been etched. Remove the scale with a stripping pad and paint over with regular epoxy primer, then sand flat. You'll probably need to primer again w/ another sanding after.


(Correction above . . . make that Xylene not Xylol)

Re: NEED HELP REAL BAD-Painting jon boat

You might want to try miratic acid mixed with water apply with a brown scotch brite pad.Rinse with water while scrubbing with a fresh scotch brite pad.Now depending on how much water to acid mix to use try starting with 1(one) gallon of water with 1(one) cup of acid.You want it to just start to turn the metal a dark color.It doesn't need to set on it for too long.Just make sure you rinse it well to remove all of the acid(lots of rubbing with pads)You'll know if you got all residue off if there is no white powder residue when it is dry.Good luck. P.S.AVOID INHALING FUMES

Re: NEED HELP REAL BAD-Painting jon boat

Yoiks!

Muriatic acid, otherwise known as hydrocloric acid (HCl) is right up there with Sulfuric acid (H2SO4) as the nastiest thing you can find on the planet. It should be used as a last resort only and at that with only proper safety gear - full eye protection (goggles not glasses), gloves, respirator, and a rinsing station nearby. When I taught labs there was a very large lecture on safety procedures, instructions, and emergency responses before this stuff was ever dispensed. Even then it was relegated to under-hood usage only.

Really, it should never be considered a casually used compound - I can't stress that enough.

now Murray is no more
for what he thought was H2O
was H2SO4

Re: NEED HELP REAL BAD-Painting jon boat

Y'know the other thing that should probably be mentioned is . . .

Why remove the latex primer in the first place? It sounds like it bonded just fine to the paint beneath it, and it's not like the aluminum really needs any protection, especially in fresh water (this is a fresh water boat, right?). Why not just put a finishing color coat on it and see how it stands up?

Re: NEED HELP REAL BAD-Painting jon boat

WOO HOO!!!!!!!!!!!!

I bought some stuff called latex paint stripper by Liftoff inc. It works great!

I sprayed a section of the boat and waited about ten minutes. hit it with the pressure washer and it came off like water! the original Lowe factory paint is still hard as a rock.

I now own every paint stripper known to man. Oh well lesson learned. Still have a lot of work ahead of me, But at least now I know it can be done.

I ordered my paint from Cabela's. I got a gallon of the Parker duck boat paint. Bay Gray is the color. Need to get the correct primer this time and I will be good to go.

Thanks for all the help!

One last question. Will Zinc Chromate paint life the existing paint like the etching primer did?

 

[PIPER354]

Re: NEED HELP REAL BAD-Painting jon boat

As far as keeping the latex primer on. I would rather go through the trouble of getting it off first and not have to deal with it later. I plan on doing some pretty serious mods to this boat and do not want to have to worry about repainting it.

I did paint over the latex with some oil based paint and it seemed to hold up well. but I have bad luck sometimes...

Re: NEED HELP REAL BAD-Painting jon boat

Good to hear you've got your problem solved.

The zinc chromate paint has etching compound in it, so I'd be willing to bet it'll lift up your old paint.

Only one way to find out for sure though.

Re: NEED HELP REAL BAD-Painting jon boat

um lol ever try using a heat gun warm it and use a scraper to remove it and then after thats done presure wash the exess off works fast n easy

 

[PIPER354]

Re: NEED HELP REAL BAD-Painting jon boat

Don't need to worry about it anymore. After 2 weeks of work and $150 in chemicals my boat is olive drab AGAIN and ready to be sanded, primed, and painted.

I hope I learned from this lesson!

Some mistakes are just so fun making you have do it over again.

Re: NEED HELP REAL BAD-Painting jon boat

I was going to do the same kind of mods until I obtained the nightmare project that I have now.
