Hey all,
See attached pics, I have some minor bubbling coming up at two of the feet bases on my platform. I'm looking for options if anyone knows how to take care of this without having to do a full removal and powder coating of the entire structure. The rest of the coating is in perfect condition. I was also looking at just spraying the platform in line-x if my only option to fix the bubbling is to re powder coat the entire platform. I also have used the rustoleum truck liner before and that seems to have a good finish but I'm not sure if that will hold up to saltwater as well? Any thoughts are appreciated, worst case scenario it gives me an excuse to finally weld on a fold up backrest to the platform.
Thanks,

Easy fix.

It may be over kill but this is how I've done it in the past.
Sand the area. Alumiprep, alodine, epoxy prime, paint.

Thank you, I will research that option and see what it all takes.

that's the correct way to put a coating on aluminum !
the chemical etch prime is vital - fail to etch prime,the coating WILL fail !



powder coat - once it begins to pop and bubble,it's all coming off.ANY attempt at repairing it,won't end well. powder coating looks nice,but it will not last - especially rod holders.most rods have metal butts,a metal butt being placed into a pipe,on a moving platform - think about that a few seconds....once the powder coating gets scratched/nicked,it will begin to peel and pop.soon as the mounting screws are tightened in the mounting points,the powder coating in the area is compromised...

Sorry, ya I did not know how to set permissions. You should be able to see them now.

If you are on a budget. Little 90 degree pneumatic air grinder with 2 inch scotch brite disc. Clean it all off nice and respray with a quality paint such as an outboard paint. If you want perfect it will require re powder coating.

Thank you, I was wondering if there was a cheap fix, I guess I have no issues waiting a year to do the whole platform, I just hope that it doesn't eat away the metal and jeopardize the integrity of the structure, I think I overthink these things though

Why go through all that trouble just to skip the most important steps of proper cleaning and priming? An extra $45 in chemicals and it's done correctly.

yep, I already got the epoxy and primer to do the project. Now I need to go to the store and find some "time"

This is why I don't have any powder coat. My buddy did his platform and casting platform. I am waiting to see

Perhaps. My repair is going on 6 years. Looks good as day one.

 

[jmrodandgun]

Well damn. You might be onto something. I wonder if the flap disk is what gave the paint such a good hold.

Once you get it coated correctly use TefGel on the fasteners and never worry again. Good stuff time tested on my skiffs and many sailing vessels. Kills the dissimilar metal issue.

What grit sandpaper(s) would you guys start with and end with? Also, is that alumiprep or some epoxy what I put on the bare metal when I get there to stop the corrosion?
