Default Fixing scratches in aluminum?

Wilma banged up my boat a little and the most severe damage are deep scratches in my radar arch top. It is polished aluminum. Is there any way to minimize the how bad the scratches look? Maybe sanding and polishing?

This is no joke but you should keep the scars with pride Bud. You boat survives a hurricane!! There are number of compounds that would help remove some of that but they seem to be deep and I would say to fill and polish back sanding that will weaken it. There was a recent thread about a inexpensive aluminum weld rod with a torch that might do a great job. http://www.aluminumrepair.com/

Good luck,

Yeah, I think Steve is right, the best you can do is attempt to hide em. I'd try getting a small can of silver paint, daub it into the scratches, wipe off any excess and let it go at that.

Difficult to see truly how deep they are from a photo, but if they are fairly deep, I'd leave them be - in order to make them "dissappear" by abrasion (no matter how coarse or fine), you need to remove all the surrounding aluminum down to the depth of the scratches. If they are deep, that would mean seriously weakening the tubing.

Two things you can do,

1] buff rough edges down and live with the BATTLE scars of 05 , or

2] have a new arch made , this may take awhile do to all the boat repairs going on right now.

Trying to fill with cheap wannabe stuff will make it look worse and trying to repair with T.I.G. or M.I.G. will prob. warp the tubing.

If that's all that happened to the boat, I would claim the battle scars.

No new numbers with the new engines. I just got them rigged up on Thursday before Wilma. I have not had the chance to run it yet and now it may be a while due to the power and gas problem. And whats worse is that the new engines got scratched up a bit as well as the boat it self. I was able to buff out the boat and engines to a satisfying level.

I am not looking to do any major repair on the arch with welding, I know the scar of Wilma will always be there, I just wanted to smooth out the rough edges.

Scarab; Its hard to tell just wereyour damage is on the Alu.rail in the Pics. but, you can do a tight wrap of 1/4 inch (or less) of Nylon line over the damage. This would hide the damage and make it look like a hand hold. You have to do this on port and star side to make it look like it belongs. Just a though. Ginrickei

WELDER makes sense . . . I also was a welder in an earlier life

Just buff out the sharp edges to prevent cuts etc.

Lucky that was the only damage your boat suffered
