<HTML>Thanks, I do not want products I want processes. Tell me what you do and how you do it to remove scratches. I do not want to know this for my own use, I want to know it because someone asked me and I did not know what to tell them definitively. I could logicallly figure it out, but not having any experience with this personally I do not know if it will work or not.
The Flitz Ball does wonders on oxidized aluminum, but what about that with scratches?

<HTML>Bud, you basically do the same sanding processes that you do on a painted finish, or for wood.
Have to "level" down the surface, but each surface may be different.
If heavy billet, or cast, you got a lot to work with, if a "grill shell" like on a class 8, then a bit different process.
Aluminum oxidizes from not only the outside, but also from internally.
To know this is important, as the various alloys of aluminum will vary, creating different "density" at the top level of the material.
There are some aluminum alloys that will exhibit a very "soft" substrate, once you have sanded and removed the scratches. This may be overcome by "acidizing" the surface, as the acidizing process creates a small hard surface again for the aluminum.
Unfortunately, the acid required to do this is the danger HF, diluted to a 4% to 8% mixture.
Just some of the answers to a very involved set of processes for handling aluminum scratches, polishing etc.

Do it right or don't do it at all!

<HTML>Bud,
We do a great amount of this work on aircraft and one off billet wheels. If you need input feel free to call. Ron hit the process on the head and I can follow-up with available products to bring back the shine. What is the aluminum on?</HTML>

<HTML>Bud, Grumpy and Renny are dead right on,as I have done quite abit of experimenting on cleaning over the road trailers and tank trailers. One thing that Grumpy said thats so,so, true in acidizing, this changes the substrait,and the buffing changes course. This in what to use,and when to use it. the folks that I buy from ranges from rough sticks to a compound type material that I purchase in 5 gallon buckets for the different grades of aluminum. I'm not going to dazzle you with a bunch of B.S. because I can't.My chemical suppliers help me/us out a great deal, when I call for advise. I don't know who all makes the polishing equipment in this industry,but their Drum Buffer/polishers will be hard to beat. I have even got out the old Heli Arc to repair some truck rims, before acidizing to clean,the before.
Scratches,once again is like working with deep scratches on paint as Grump said. 1st time working out some scratches on a rear bumper on a tank trailer,and went thru about 4 buffing drums. Then walah! I tried some 220grit quickly moving to finer paper, then to the hvy compound, to minimize metal extraction/removal then to polishing compound... This probably don't help but, it's as good as I can do............. Brandy !</HTML>
Thanks Webb Master for getting me back on Line!.....Brandy

<HTML>Renny Doyle, you say you do airplanes! Do you know anyone who sells some detail process info to get into this business? Some of the trucking companys I do business with have their own planes,and have to wait for trips to big citys to get this service. Similar to getting their tankers and coal buckets cleaned and polished. I feel like air planes would be of a definate different animal than working on a 18-20 wheeler used to haul coal/petroleum or chemicals. Probably too many rules to comply with,and probably have to have the recovery systems that the Mobile Detailers are plagued with...Appreciate any info on this ....... Brandy !</HTML>

<HTML>Bud, I sent you an Email that I hope will answer your question as how to fill scratches, then leveling them for compounding to final polishing. I hope this helps. I can't thank Grumpy and you enough for how helpful you guys have been to me.....................Brandy !
I didn't put into the email the different colors of compounds to use.
Green hvy, Red Medium,and white is polishing,and I use white rouge for the final polishing.My supplier said that the white compound is all I need, but I get the mirror finish quicker, after the red, with the white rouge sticks. Remember we're working on big truck equipment and truck rims. I did the inside of a drag car a friend of mine helped his son build,and worked the whole thing with white rouge stick only, then used some diamondplus to seal it. They make a clear sealant that I did spray on one customers trailer,and used a HVLP Gun set up to do so. He had the money and I had the time...........................</HTML>

<HTML>No Renny it's a Specialty Sealant Polymer. AirMark sells it $35.00 a qt or $115.00 a gallon.......... Put it on HVLP Gun. This product is the berries,awaiting to see how long it lasts. It will go thru a few truck washes,and will return home in 2 months, so to say the least, it will see all types of weather (Snow & Ice, thru Hot & Sunny) I'm interested in seeing what the road salts/Sand will do as far as deteriation,especially the under belly of the Tanker. This KW has a salt/sand spreader ahead of the Tandem Live Axels.With the big flapps, it still does it worst to the belly of the Tanker. Renny, better close,as I'll have some of the guys telling me to take this info and shove it, as it doesn't mean @!#$ to this forum. Great Bunch of folks on this forum.
P.S. you have a great web site,and I may try some of your chemicals.
Try some A&H Buffing equipment,as they can't be beat.I think they got some Timex in them, take a lick'n and keep on tick'n. I set my Air Comp on continious run,and we run 3 drum,and one flapper wheel buffer continiously.......... Brandy</HTML>
