I took the truck out today and decided to go around the block.



I pulled the truck back into the garagae and this is what I found!!!!!!!!

the swirls were only on the hood!!! I didnt touch the hood with anything!! All i did was drive it! ***??????????????????????



As you know i wet sanded and polished it to be like glass.. (see other threads)

:bawling: What happened???



HOW IS THIS POSSIBLE???????????????????

Is the paint new? If so its probably still a bit soft and easy to swirl.

28 year old paint hardly constitutes new. The owner has had the vehicle for 27 years and claims he's never had it repainted.
 
I read your other post and I'm pretty sure you didn't use filler polishes or anything. You weren't using filler polishes were you?



You can see sanding marks amidst the swirls, it seems.
 
I can only think of 2 things. Either you used something with filler in it or you didn't fully remove them. Which thats what i'm thinking cause i still see sanding marks which is a good sign of not cutting thru it all.
 
I could only dream something with fillers could hide those original swirls so well. I mean, they were deep! I guess the only thing was I didn't remove them before.. but why did they disapper?? Crazy.
 
It almost looks like you didn't remove all the scratching even with the wet sanding.

Looking at your pictures on the other thread the pattern looks the same. I did notice that the fluorescent light was not on. I find this to hide fine swirls and scratches some times.

The scratches look to random to be swirls.



Did you use wool?

No i used an orange foam pad....... I had the truck out in the sun after I finished.. no swirls at all! I also had th fluorescent lights on and off for pics.. absolutely no swirls! I would understand if i didn't remove all the swirls and they would still be present. But for them to dissappear and then re-appear in full force??? Nutz!
 
perhaps the hood was repainted at some point, wether it be 20 years ago or what. but ive noticed repaints will always swirl 50x easier than a factory paint job.
 
After seeing that many times in the past, it is paint failure for sure. The pigments wearing off are the first sign. Very common on hoods due to the excessive engine heat and buffing too much. For it's year it has gone a very long way. Just need the hood to be re-shot.

I am surprised the paint lasted that long. That is in beyond excellent shape and extremely well taken care of.

I agree its paint failure... but answer me this if u can. Initially I tried PG and HTEC and NOTHING happened to the paint. It was still HORRIBLE.. (Paint failure for sure). Then I wet sanded and buffed and it came out like glass! Then it returned to horrrible when i drove it out in the sun) WHY??? How could it look like glass if it was failure???
 
When a finish is smooth and will not polish out then chances of the pigments in the ss paint are far gone. The wetsanding took off the dead layer and just brought out the new purities in the paint which will only last for a short period unless you protect it with a premium product that has high UV protection. The sun will drain the purities out of old SS paint very fast if not protected with a UV sealant.



When you wetsanded and polished all you did was brought out the new purities (which is on a very thin line) but will shortly fade away in an hour from the sun and the engine heat. Mostly common on hoods.



I have dealt with the same issues before with an older porshe 5 years ago. I have even seen it on clearcoated paints also in the past that have thinning clearcoat.



Funny, I do have an old 83 New Yorker to do next week for a friends mother which has the same issue. He has buffed it out and looked great until 2 days later. I will redo it and protect it with z2 and see what happens. I'll let you know how it turns out and see if that helps.

thanks for that explanation.. that makes sense.. What do you think is the best UV protecting wax that I have? I have: 476S, 845 collinites, Natty blue, NXT, Pinnacle Souveran, P21S, Menzerna FMJ, AIO, Jeffs Acrylic Jett and Optimum spray wax.
 
If this is what's happening (I haven't checked the other thread so I dunno if I was on the right track), I had similar problems on the Volvo (and I'm on the verge of them with the Jag).



I did OK with a Meg's #80/#5/Collinite 476S approach on the Volvo, and it was an outside 24/7 car. Carnaubas always seem to work better for me on ss, and *especially* on not-so-healthy ss. Probably would've looked better with #7 or #3 instead of the #5.



The Volvo held up for *years* after I'd pronounced its paint "dead". The Jag's ss metallic lacquer is still holding up well even though people have been predicting major failure for a long time; I did finally have to have a few areas reshot, but most of the car is still OK even though its ss metallic has turned "blotchy" in many places due to thinning and UV damage. I can't do any more correction on it though.



I'd hit the hood with a Meg's glaze and then apply plenty of 476S. Souveran wouldn't last long enough IMO and that's gonna be the main thing for this one. This is one case where the old "feed the paint" stuff *is not* really BS after all- get it to soak up as much glaze as possible and then do the same with the paste wax.
