Please help- stripped and started polishing- white spots

We started stripping the clear coat - used the orange Citristrip and started a test polish area with NuShine F9. We have went over it several times with the F9 and still have these white spots - cloudy areas that are smooth to touch. I'm curious if anyone knows what it is. I can't help but to wonder if the clear coat is still somewhat present or if we should continue. Click image for larger version

That's why a pro polish job can cost $40 a foot. You probably need a lot more polishing, but try some paint thinner on a rag and see if that removes it. Worse case scenario is filiform corrosion which is extremely stubborn to polish out, but you would have seen that before you started polishing. What year is your stream?

Please help- stripped and started polishing- white spots

My guess from what I can tell from the pictures might be tiny pits.

If this is so , they may polish out with lots of polishing, or you might need to wet sand them out,

Of course this is hard to say from a picture , the spots could be clear left on the trailer surface.

If paint stripper makes it possible to polish them out .... Well you get it.

Tell us what your polishing with. I bet its not a cotton wheel. A pad will never do a good compounding.

Welcome to the polishing blues. Judging by the reflectivity of your polished aluminum, I'd say you're doing great. I can see the front porch quite nicely in the distance in your aluminum mirror. And you are still compounding with F9.

Maybe you rinsed the stripper with hard water. Bare aluminum water spots quite easily. Your white spots look like my white spots.

Every rain event, every passing robin, every stuck leaf on your shinny aluminum will stain it as it reverts back to it's dull gray self. You have to get used to imperfection less you park your trailer in a atmosphere controlled bubble and never use it.

Don't fret, do the finishing polish with your F7 (works well) or S (which doesn't do much) and enjoy. Then polish again next year, and the year after that. I put a polymer sealant on mine (NuFinish works for me) which lasts a little longer than wax.

Airstream switched to a brushed finish and clear coat years ago just to relieve all the maintenance of a polished aluminum trailer. They are dramatic to look at, and a lot of work.

True enough, a foam pad won't cut it. And a real buffer is a must

Year is 1967. We are using a variable speed Dewalt right angle polisher with 7 1/2" wool aircraft aluminum polishing pad and F9. In my opinion the trailer looks worse after stripping it. I hope that this isn't a reaction from the stripping product itself. We left it on for about 10 minutes and pressure washed it off. We do have hard water but I dried the area with a towel.

Polish by hand in the cloudy areas. If you don't get black stuff on the cloth, you still have clear coat. Citristrip is fairly mild, as strippers go. It may need more time than 10 minutes to get all the clear coat off.

Our '66 Safari took a couple of applications of Aircraft Stripper in some areas.

Citrastrip can be great stuff but it needs TIME! No way, no how, did it strip your clear coat in ten minutes. When I stripped my interior panels it took at least four hours and often overnight to strip the paint. I've left it on for far longer with no problems. I'm betting your problem is left over clearcoat, Try stripping an area a couple square feet with aircraft stripper, it's nasty but works way faster than Citrastrip. Then polish again and see what happens.

People who are disappointed with Citrastip usually make two mistakes, they don't leave it on long enough, and they don't keep it wet. It helps to cover it in plastic.

I know plenty about polishing, and some days I know nothing I spent all of last summer polishing and it truly is an art form ......

1)Where does one buy aircraft stripper?
2) other than using plastic, how does one keep the Citristrip "wet"?

1. Any auto parts store - Pep boys et al
2. Keep it in the shade , or do it at night, power wash the next morning.
