My Personal Paint Thread
Google Moffett Hanger One images if you want to see a real birdcage. The exterior is completely stripped off. Disposition unknown!
Parts of it are spectacular, but no matter how badly I ground on the rear deck I just couldn't seem to get through ALL of the orange peel, and the tops of the rear fenders also show some 'mottled' appearance where I can't really tell if I've gone through the clear or what, but it just doesn't look right and I'm afraid to sand on it anymore. I will post up a couple pics of that tonight so you guys can tell me what you think, but as it stands right now I think I'll probably be re-sanding the rear deck and re-clearing the fender tops and rear deck to get the right finish. It worked really well on the driver's door, so at this point it really seems like a viable option.
Anyway, for what it's worth, here's the latest...

Fire Away!!
Looks great from the pictures... How many coats of clear did you shoot (wet coats)??? What progression of grits have you gone through??? Hope you don't have to re-shoot...
Long arduous process to sand, buff and polish... Certainly can be the most stressful step as you are "Almost Done!!!" An "oops" now will be very painful...

I think I read that when you recleared the door due to sanding through you didn't rebase. You will probably get better results if you spot in the base over the sanded through area bridging over the broken edge of clear.
If the broken edge should lift you may have to spot seal it first, then spot the base and reclear the entire panel.
This way you won't see a color difference or ring where it was sanded through.
Good luck

I went around the car four times. I will have a minor confession to make at the end of the thread, but suffice to say I had a little problem with orange peel. Every time I had shot base/clear in the past, though, I had problems with runs and solvent pop which is especially infuriating, so I was happy to have four good coats of orange-peely clear which could be sanded smooth. I'll drop a couple more pics of the fender tops tonight (between the top crease and the sail panel) where there is this wierd kinda moonscape-lookin' finish. I'm afraid to keep sanding on it for fear that it's already through the clear, but if I get enough consensus that it isn't I'll go ahead and sand it level and polish it...more to come.
If you think you have sanded through your clear but are not sure, take a look at the sanding sludge and see if is showing any color. If your still sanding clear it will be white.
Good Luck

...Thanks again all. I'll be off work until after New Year's after tonight so [hopefully] I can get some real work done on this thing, like get the rest of the car color sanded and buffed...that would be nice
While I agree not the best pictures, it still looks like peel to me... Is this something you can "live with???" I probably know the answer, but thought I'd ask... You run the risk of breaking through if you take the sanding deeper... I would definitely put some tape on the sharp edge of the top of the quarter panel when sanding/buffing... Only you know how much clear you shot in this area, and how much you've sanded off so far compared with the rest of the car... This looks like an area that could accumulate extra clear because of the angles...
Have you showed the pictures to the guys that sold you the clear??? Be interested in their take...
Sorry can't be more definitive... Craig will probably chime in today to provide a pro's perspective...
Might also be worth a PM/call to DUB, BarryGa and/or Markids for their take...

Putting the first coat of clear on dry is not how the pros do it. As you have learned the first coat sets the course for how the following coats will look. A wet coat on top of a dry coat will not reflow it. It will just keep making larger orange peel as it builds up.
Even if you have 4 coats with deep peel, the millage(thickness) of the clear at the bottom of the peel is not that thick. You can block the top of the peel off and if you can stop sanding before hitting the very bottom of the peel you shouldn't go through, although as you work up to finer grits and compound you still will continue to remove a small amount of clear.
Another thing to consider is even if you don't go through but the millage of clear is very thin it will not have much integrity against UV rays and general durability will be weaker than it should be.
Good luck,
Craig

With the rear deck, the clear at least appears thick enough that I can re-sand the worst spots in about three or four localized areas (say,1500-2000-Trizact) and then repolish the whole deck...I feel pretty safe with that; and last Sunday's emergency room trip sort of contributed to it.
With the fender tops, THEY look eerily similar to what I saw on the driver's door and headlight door just before I started sanding into clear. As such, I'm pretty hesitant to go to the bottom of those two spots... Would it work to sort of 'dust' that part of the car with, say, 800 and then clean, mask, and apply a couple more localized clearcoats?
I COULD let them go; it would still be an overall amazing car to look at in the sunlight, but there's just that nagging knowledge that it's not quite as good as it could have been and if I'm gonna fix it sooner is better than later.
I do get what you're saying about clearcoat application, but my neighbor/painter/friend helped me with shooting a couple repairs on a friend's car about a year ago and he showed me the dry-wet-wetter method, which worked better than anything I had yet tried and prevented the solvent pop and runs that I had been experiencing. I had previously found that solvent pop doesn't sand out, and runs get full of air so that if you can 'cut' them down they still don't look right. I can live with peel, because as long as there's SOMETHING at the bottom of those little craters you can polish it out. I'm just not quite positive that there's something at the bottom of these, and even though I made four trips around the car it is still possible that I might have repeated the same mistake four times...
One thing for sure, with y'all's help I have learned a LOT through this whole process, and it really has made it worthwhile. Maybe we can all meet in some small-town bar in the middle of the country one day after this and share a couple pitchers...thanks again all...
