Clear coat Polar White from Hemet?

I don't think the clear coat will stick to the polar white. It's pretty slick. We've painted it most of the time, involving scruffing and prepping. My 58 Cardinal stayed white and it was very pretty.

By saying “it stayed white and was pretty” on your Cardinal, do you mean on that trailer you just left it polar white as it was coated from Hemment and it stayed looking good (ie no need to clear coat)? 

I do do like that shade of white. Any issues with scratching or durability? Did it stay glossy?  If so, I might reconsider my paint strategy 

 The polar white seems to be holding up fine. But the PPG paint seems more durable. How durable does it need to be, that is the question.

I did not use the seam sealer but  I did use some gutter sealer in key areas that seemed more susceptible to water leaking in and over the staples.  The 1 inch wide putty tape did a good job sealing. 

I  use a double layer of putty tape at the vent and  the front & back window. 

Single stage automotive paint is what should be used if you are going to paint your trailer. The polar white that the metal comes with scratches fairly easy. So you may want to paint over it. The reason for single stage paint with no clear coat is advised is because a clear coat makes it very hard to repair scratches. You can just buff out a scratch with single stage paint.

Something everyone should be made aware of is that for some reason, (probable EPA crap) the manufacturers of the metal skin changed their formula for the clear coat on the back side. Mill finish side. Now, because of the change, if exposed to sunlight, within 6 months it begins to peel. So if you are thinking of a mill finish for your trailer you can't do it anymore. I don't know what the answer is to this problem. I'm thinking that if I want a mill finish trailer I will use RAW aluminum and etch it, then clear coat it. I have no idea how that would work though.

I have no idea. Never occurred to me to ask. But I don't believe that the J Rail has anything on it anyhow. I think it is raw. I have welded J rail with Alumi-Weld and I didn't see any coating. On mill finish you see it when you heat it up. But don't take my word for it. I really don't know for sure and now I want to ask Steve about that.

I've never polished the J Rails. I just put them on raw but cleaned with alcohol. That gets all the oxidation off and they look great.

This just happened a year ago Vikx so you are OK. And Steve will sell it to you but you must sign a waiver that he told you about it and you are still going to use it against his advice so you don't sue him later. That's what happened. Someone sued him over it. I saw photos of the trailer that used the mill side. It was horrible looking. I may still have that photo. I'll look and see if I can find it. 

I think Interstate has always sold raw mill finish haven't they? And what I need to know is how do we keep the oxidation down without some kind of coating???

It was suggested to me to wax my new camper aluminum. All the wax products I have found have been for painted surfaces (like a car). So I'm at a loss. I thought, hmm.., wax paint, polish metal? Does anyone have a suggestion for a wax product for mill finish aluminum?
