opinions - should I remove the bottom paint on my tinny ?

[TinnyTime]

What say you ?

I keep it trailered, .... I bought the boat like this.

Also, if I do remove the anti-foul.... should I Shark Hyde the hull ?
The factory finish has a clear coat, but that would be removed along with the bottom paint removal (un-avoidable).


pros of removing:
- less corrosion (salt gets under the paint in spots, and corrodes it worse than if bare aluminum and kept clean)
- The bottom paint runs with the rain water and stains my trailer.








Theres a grey sealer coat UNDER the anti-foul paint which is much more difficult to remove.
I tested using an eco-friendly paint stripper.

I would, but I would also get a wrap instead of paint as well imo

Why do you recommend getting a wrap ?

They look great, easy to repair and last a long time

Why do you recommend getting a wrap ?

And imo to protect that shiny alum hull against rub rails and wood on the docks. I dunno it may just be me lol

I don’t think a wrap below the waterline would hold up very well on/off the trailer frequently. Only recommendation if you do decide to remove the paint is to get it blasted off it’s not a fun job there are some epoxies that can be painted on to protect from corrosion or like you say shark hide or nyalic would work.

Reviving an older thread....did you end up removing the paint? If so, how and did you use Shark hyde after? I'm in the same boat right now. I moor mine for 5 months of the year, but I'm thinking it would be far less headache to just clean the boat monthly instead of maintaining the paint and worrying about corrosion issues. I also find any chipped spots in the barrier coat seem to react with the small amount of copper in the Trilux II

Its on my to do list.... but haven't yet cuz it will be a BIG job.

I've only removed a test spot so far, but it didn't go so well, I need better chemical, Ive been recommended aircraft stripper.

I agree with you about the chips and making the corrosion worse in those spots with the copper in the antifoul leeching. I have this happening.

I'm not sure where you are located but langley u blast offers a soda blast for bottom paint ive seen there result on fiberglass and its amazing sure the same could be done on a tinny

 

[TinnyTime]

Wow, that would be ideal. I'll look into it thanks

 

[TinnyTime]

Update, I'm still in this project....
I just found Ocean Pacific Media blasting in Duncan by reading thru the forum.

I'm reaching out to them, hoping they can help with a soda blast for reasonable cost.

I used the online form.
But since then they've contacted me saying to call Jeff from GNC soda blasting.

I'm going the DIY route, and blasting it myself in my driveway. Either using crushed walnut shell (expensive, but real easy on the aluminum.) or chushed glass (cheap, but more aggrssive)

Got a big tarp to catch and recycle the media.

Just gave it a quick trial run so far....
Waiting for a weather window now...
Wish me luck...

@TinnyTime how did the diy route work out?

 

[TinnyTime]

Haven't done it yet.... but I have confirmed I need to as remove it....
I tested the bottom paint using aquarium strips, and confirmed its copper based.
Even tho there is an epoxy sealer coat under, copper is no good.

To to the sand blasting, I need the air to be dry so the pressure pot does not clog.
I need an air dryer system..

I could rent a BIG gas powered compressor from Sunbelt to do the job

Ive also been considering taking the boat to the marina, getting put on hardstands and getting their subcontractor to do it.....

I took mine to a shop and had them blast it. They forked it off the trailer I think. Was on a budget, so told them to go as far as $200 would get it. Took it home, pulled it off the trailer, and sanded the rest off with an angle grinder sanding pad. 16’ Lifetimer

That seems cheap. Curious which shop ? I should call them up.

By the way,...I also have a beloved 16 Lifetimer CC !!!
