Polishing Windshield - With a Polisher ?

[DIY1111]

My boats windshield has a lot of water spots. Nothing! takes them off - no chemical and most hand-mechanical things. The only thing I've used that works is a rotary polishing wheel with 3M Compound. I have more water spots - not like on a wine glass, not heavily etched either - and some light scratches from trying to spot-scrub with 0000 steel wool.

I've read about the use of serum oxide `and a DA polisher. Anyone have experience with removing water spots and light scratches ?

Thx

I polished my windows prior to putting the tint on them to get rid of minor imperfections.

it takes a lot of time to polish glass

I did it on my chevelles windows with the serum oxide. I used a felt wheel like this. It works but as mentioned is alot of work for scratches. I think water spots would be fairly quick tho.

Quick being a relative term. I was taking some nasty 50 year old scratches out. Compared to that it is childs play,

Make sure it is actually glass tho. It will eat plexi alive dull it and you wont ever make it right again. Plexi is regular rubbing compound and a rotary buffer and a wool pad.

Thx for the responses. The scratches are really superficial. I want to polish all the glass with a wheel of some sort - to cover as much 'ground' as I can. Can the serum oxide be used on a larger pad polisher ? And, is it one step, or multiple steps to get it to be right.

The other PITA is that I have a hardtop with aluminum pipe work that makes window access challenging in some areas...

No it is a one step deal. Do it till your satisfied. It will work on anything you use it with. Bigger the area on the pad the longer it is going to take. It is friction and the wider the area the lesser the pressure is. You are literally buffing the surface of the glass off. It gonna take a while.

You mix the powder with water and make a paste. Keep a spray bottle of water to keep it moist. Use it like buffing compound. That is literally what it is. Just a different medium.

For what your talking about wanting to do. I would use a variable speed rotary buffer and a wool pad. Google it there a few good how to videos floating around.
