Anyone had any experience of clear coating tinnies ? ie : ease of application. effectiveness, do you put it on the underside of the hull, how long does it last, and does it brush on ? Perhaps the most important question ..... would you do it again ??? |

I have nylac coated below the waterline of my last two boats and have been happy with the results.
A good clean and a dust free enviroment seem to be the key for a good finish. I applied with a brush to cut in and a small foam roller for the rest.

| yep had nyalic on my last two boats, above water line though and found it hard as nails,except where petrol has been in contact.Big thing though is who puts it on can make all the difference just like most things |

As you can see, there are differing opinions ! I was planing to "do it myself" and perhaps, just topsides only. my new boat is going to be a 4.1 mtr pontoon open boat so there will be a lot of curved panels. I was hoping someone could say that it could be applied by brush. The boat will be brand new when it arrives, so i guess just a plain old H2O wash, dry and then paint ? No acid etching for new ???

Not much help from me Contract..except I have a Surtees 6.1 with topsides with Nyalic.... awesome looking! Keeps the boat looking new for years, especially if high wear areas covered with Scuffproof (a clear palstic film  ) areas liek transom/anchor well area etc. I wouldn't bother with below the waterline myself, but topsides on ali. looks very good.
I guess with all jobs like this, it's all it the preparation. Good luck

When I was buying new they had a new one somebody orderred but then changed their mind and wanted it with Nylac. They would not do it and made another one because of the preperation and greese off all the hands thats been on it so I guess the preparation is pretty important to get a good bond.
I have it top sides and like expresso find it great altho has washed off under the fuel overflow. The clear coating around anchor sounds good

I am with Dohboy on this one. Have Nylac on the topsides of a boat and wouldn't do it again. I love the look when it is new, but it is very hard to patch when it gets scratched due to the need to acid wash again. Definitely need something on top of it everywhere people stand on the gunnels when boarding etc. Nylac HATES petrol, so think about what you will do around the filler and breather.
Personally, I find paint easier to look after than Nylac. Just take a chip to the local store and they will colour match a spray can for you. On our 5 year old boat the paint still looks great even though it has been patched few times. The Nylac is starting to look a bit sad and I am dreading the thought of trying to fix it in another year or so.

Hi, I'm sure you'll find that no matter what you put on it, Nylic or Paint, you'll still need to etch it to get ANY gunk or oxidisation off or the coatings won't adhere properly, even though it's new, it'll still have crap on the surfaces from the factory that'll need to removed first. Best of luck Paul ------------- I don't want to be a pie-I don't like gravy. |

alidean acid [ clear for clear finishes] or amber for painted finishes,
this is a pre-clean for aluminium boats,followed bye zinc cromate etch primer for painted overcoats,within a 12 hour period or delamination WILL HAPPEN
contract FORGET NYLACK as said bye the guys its not solvent proof [petrol diesel etc ]
dupont make a garrented 2 pack poroduct that is tops !!!
as long as it is applied bye an aproved aplicator [not brushed on ]
DO IT ONCE ... DO IT PROPPERLY OR DONT DO IT AT ALL
my best advice
search my posts i have given lots of advice in the past on this vary subject

I had my boat done and it is awesome. Easy to clean and makes it look
like new. Very happy. Also was half the price compared with paint. ------------- Nothing else to life but fishing and beer!. |

I put a 2 pot enamel on my boat years ago, very hard wearing, had anchors, chains dredges dragged over it. Am looking at a boat with nyalic on it that is looking awful. Any bright ideas to get it off other than a big tin of petrol and a gas mask? |

Nyalic was basically designed to prevent corrosion of ali where seawater has been on it without going for a painted finish. It would be good to do the whole hull if you do anything at all, as the bit that's in the water needs as much protection as what's out of it. Plus it avoids the line effect where one isn't and one is coated. Nyalic doesn't do any solvents, some cleaners and even skin oils that are acidic. Glues can remove it, so be careful what plastic you stick down onto it. Basically Nyalic is a pain in the arse, it is great when used within it's limits but as a fire-and-forget coating there are other better options.
Next: Zinc cromate primer on ali? WTF?!?!?!?!?!?!  Zinc cromate primer will do funny things over time in seawater, the zinc drops out through electrolysis and the rest of the paint will fall off. Zinc cromate isn't specified for immersion in water... Use two-pack epoxy or vinyl etch or don't bother painting... |
