Compounding causing crows feet?

So I was starting to tackle the hood of this 2000 chevy suburban with m105 and what i saw after the compounding stage was this...

Some of the spots are chips, but 95% are cracks in the clear coat. I really didn't notice it before the compounding so i have a suspicion that the buffing caused the crows feet or aggravated preexisting cracks. Upon closer inspection, the front of the hood has some very minor cracks but the area i buffed is terrible.

The owner admitted that the car was about ready for a repaint and he wanted me to get whatever life was left. I am really hesitant to touch any part of the car now afraid that the clear will crack all over. This chevy swirlburban needs some serious paint attention. So far i have tried 105 and 83. I am not all that great with the 105 and the 83 isn't quite cutting it. I am using a rotary, but i have a PC i can break out if that would be better. I would greatly appreciate any advice.
 
Oh hey MBenz, are you on Benzworld?



Ugh! Terrible modern paint, it's the same with Honda paints... My friend has a 99 Civic with the same problem. I mean, it's not aged too much, the paint is just flat out bad. Yea, the owner abused it - but my 89 BMW 5er has seen more abuse and compounding - and the clear is still there.



Regarding those pics though, you're gonna have to send us better shots, because that's some weird looking crows feet if that's really what it is... looks like compound filling into tons of deep indentations, which aren't shaped like crows feet.



In the top photo, I see some deep RIDS in the light surrounding the center that could possibly be clearcoat cracks, but if I'm not mistaken, there are no 'branching' cracks typically seen in crows feet...



Here's what I see when I encounter crows feet...

If anything use nothing more aggressive than SIP, even that is a stretch.

What machine are you using? Pad combinations?

105 and 83 aren't cutting it with a rotary...? That's hard to believe, but a random orbital is understandable...
 
GM black and crowes foot?! My 94 Impala SS has got it bad all over the hood. It frustrates me to no end....That said, I'm not suprised to see your pictures at all. I dont think it has anythign to do with the compounding though. My personal opionion (feel free to correct me if I'm wrong) is that underhood heat may contribute to the failure of the clear and the crowes footing. My reasoning is that only my hood has crowes footing where the rest of my car does not. The hood is not the only area where the clear on my car seems to be giving up either.
 
My '98 GM hood is the same way, but not nearly as bad in the previous 2 pictures. You have to get really close to the paint to notice it, but its there, and not on the rest of the car. However, I a couple of other isolated areas of similar CC failure; the worst being this one:

To the OP: What exactly is your question?



Sorry, but I guess I'm just missing it. Do you think the compounding is causing the crows feet?

Yep, same on my friends civic - Now that you mention it, it is where heat builds up. He had one of those bras on the front, and they were most prominent under that - most likely due to heat buildup.

Cheap fkin paint.
 
its the paint, and not you....



I polished out a honda with the same problem all over the hood...I told the owner that its because he never had it detailed in 8 years and there is nothing I can do for it besides MAYBE help is slow down by waxing regularly. repaint is in order...

Yes i am benz50602 (boring name) on benz world. I recognized you from benzworld:).



Would 83 be considered more aggressive than menz sip? I am using a dewalt rotary @ 1400 with megs 6in soft buff yellow with the 83 and a megs 7 in wool cut and shine with m105. I am relatively new to the rotary so i just might have to refine my technique to get better results. This suburban is a good learning experience for me because the owner was considering a repaint anyways and it is black so it is easier to work with.



The marks really look like mini cracks. They are approximately 1 cm in length and have a crack like shape to them very similar to crows feet. The difference is that they do not brach out like crows feet. They are also isolated about 1-2 cm away from each other. I am concerned because they definately show up after working the paint with a polisher. I am guessing that the paint is in bad shape and the buffing is just too much to handle. Any other ideas of how they got there or how to remove them is they are not cracks? How can i polish the hood (megs products) without inflicting more damage? Should i be worried about the rest of the paint?

Thanks
 
I have them all over the hood of my 99 TL. I had never noticed them until I used SIP and a 4" orange pad with my PC. I finished up, and I thought, "What in the hell did I do?"
