14' starcraft aluminum deep v

[seahorse 10 hp]

Hello, i just purchased a 14' aluminum deep v starcraft boat, it has a little bit of gluvit(starting to chip) and camo paint, i want it to look nice and new i would like to sand it reseal it from the inside and then prime it and paint it, i am fairly new to this, how would i go about sanding it? wire wheel on drill? he says it doesnt leak but id like to coat it on the inside for peace of mind, got this boat for a steal of 150 bucks!

thanks for your time!

Wire cup brush on a drill or angle grinder will work, buy several of them.

i had heard that damages the aluminum is that true? and also i have heard of using different liquid sprays and such to remove paint then use the brush or sander any idea on that?

yes, be very careful using any abrasive with aluminum, it is obviously quite alot softer snd it is hard to tell how much you have taken off.

i think i would try a heat gun and scraper first, might take a bit longer but should get it off and won't remove any metal, once you get the gluvit out you will want to check for leaks and rebuck the rivets, gluvit in my book is a band aid fix, it will stop the leak for awhile but it eventually fails and then you have to figure out how to get it off so why would you want spend time and effort to get it off just to put it back on so you can get it off again in a year or 2.

and you want to watch getting it super hot in case there is rubber in between the joints but you should be able to get it warm enough to get the gluvit off.

you actually don't need to sand it, won't help adhesion at all and may actually make the paint fall off sooner, paint and aluminum don't get along, rebuck you rivets to reseal the boat then just clean it up really well and use etching primer then paint.

the eching primer is acid based and actually eats into the metal giving you good adhesion on whatever you put on after that, $3-4 bucks at any autoparts store.

and remember it is a jon boat and not going into a museum so it doesn't have to be perfect, the new paint will cover alot.

sorry no caps, broke my arm so i am left handed for a bit, not stupid.

Put in the the water and see if it leaks, and where. Sealing it from the inside is a bandaid that will repeat itself. If it has gluvit on the inside the boat has a loose rivet or two.

Well if using a wire cup brush damages a boat, I damaged the snot out of my boat. I used a wire cup brush on an angle grinder to remove carpet adhesive residue on the interior of my boat after using CitrusStrip stripper and a scraper to get the majority of it.

Before the damage:

After the damage:

I liked the way the wire cup cleaned up my aluminum and left a scuffed surface for the paint and adhesive to grip to... but that's probably just me.
