I have taken apart my vent windows so I can get them powered coated.  A few pieces have pitting, can I sand the pitting down before I send it off to powered coat shop?  If so, hand sand with 400, 800 grit?  Other options?

 

I also have original glass with some scratches.  Has anyone has success buffing out scratches?  They are not too bad, but if I do nothing and tint the windows, they will stick out like a sore thumb.  If you have done this, let me know how you did it.

 

 

Thanks

From the looks of those vent window frames, I'd say you need to start with around 150 grit paper and work your way up to the finer grades.

 

For your windshield, because it is a sandwich of 2 glass layers with a thin plastic middle layer, scratches would have to be very shallow to polish out. For other windows that are 1 layer, you can try to polish out the scratches. Keep in mind that areas that have been polished, might change the way you see out in those areas.

I only tried a product to remove stains once which werent visible until after I had the windows tinted and the polish did nothing. That said, dont know how it would work with a scratch. I have read from another member if the scratch is deep enough to catch your fingernail on its probably too deep to remove. Cant speak from experience though.

I've polished wiper streaks out of windshields using commercial stuff I got from a bud who owned a glass shop, never again. If you can buy replacement glass do it.

 

Those pits will be tough to sand out. Better to sand with 180, then sandblast, then fill pits, sand, prime, and sand till 320, then paint. Done it many times.

What would you fill the pits with?

if you use filler the powder coat may not adhere.... better check with your powder coat guy first

When plastic filler is not an option, old fashioned lead solder will do the job. It's just like any other soldering. You have to start with a very clean surface to solder to. Then you use flux to further clean & prep the surface. You then tin the areas that need filling. Finally you build up the pitted area.

 

Always wear a cartridge type respirator when soldering or sanding lead based solder.

As Joe mentioned powder coating probably isn't the thing for those parts that's why I listed paint. And as sea dog mentioned lead solder may work , however it's a pain on small parts. I'll have to test powder coating over filled pits since I always have pitted chrome "spare" stuff laying around and can powder coat. An excuse for an experiment when I'm coating other parts.

Thanks.  I sanded the pieces pretty good, still shows but not as bad.
