I would want to make sure the trailer is fully functional and does not leak before I addressed the outside. I have seen trailers from that era polished to a shine and I did not like the look all that well. Maybe try stripping a section with aircraft or heavy duty stripper and see what it looks like?
Actual sandblasting would be tough on thin Al. You generally use walnut shell media or something light and soft with Al.

The last photo I just took some toothpaste as mentioned above and scrubbed it a bit, i guess to determine if there was an absence of clearcoat it should go black which is what I believe is the result in the photo. Also I am not looking to sandblast, I believe it has already been sand blasted. Nothing leaks it was just pouring rain and I was inside checking to see if there was any leaks. Also the guy I bought it off off said he already pressure washed it as it was sitting under a tree and had a layer of grime on it

Try polishing a small area with a cloth

Try polishing a small area using a cloth instead of the kitchen scrubber. If there's no clear coat in that spot, it's the cloth that will turn black, not the aluminum. The black stuff is aluminum oxide that has been polished off.

I've seen aluminum look that pitted from pure corrosion. It may not have been sandblasted, just sat for a long time with grime all over it.

So here is an update - no clearcoat, this bad boy has been sandblasted 100%. I tried stripper and got nothing other than it on my arms and nose.

So I thought I would just jump to what I had around the house. I make concrete countertops and conveniently I have a variable speed angle grinder, I also had a lambs wool 8" buffer pad for my boat along with some marine rubbing compound and the pictures below are the result of a quick hour of messing around. So I appears that a sandblasted trailer can be brought back to life.

So my question now would be who sells the best products for polishing and buffing? And what is the fastest method? Because as you can see I have a sea of aluminium to go!!

Definitely looks like it was sandblasted in the pictures it looks like it warped the panels. If your going to polish it i would suggest wet sanding with 600 grit wet sandpaper first.

That first photo on post 18 looks pretty darn good, especially compared to earlier photos. So it looks like elbow grease is the answer to your woes! That's great--it is amazing what these A/Ss can survive and come out smiling! Congratulations!

Can we see some pics of the interior, please?

I have purchased the kit from jestco and have to pick it up across the boarder still and then will be going to town on it. I will keep my progress updates for all that are interested

Vintage trailer supply sells everything you need. Get lots of pads because you will need them. There is no fast way of doing it! Also, if you go to youtube there are several tutorials on there that will help.

Best of luck! Denise

Jestco is a good system. Take your tine and do only a few feet to perfect your method.
You might still have to strip some areas to get remnant clearcoat off. Also this era trailer will not quite give a mirror shine, but it will look 100% better.

Lucky or unlucky for me there is no clearcoat as the entire trailer has been sandblasted. Do most people remove all the things (lights, emblems, etc) before polishing or just polish around them?
