Hey guys I was trying to wetsand down the touch up paint with megs 2000 unigrit sandpaper. The car is a 2012 subaru sti. I tried buffing with menzerna SIP with an orange pad on a PC and didnt seem to get far. Any advice? Thanks guys!





 
I can't tell too clearly from these pics while viewing them on my phone, but it looks like you missed the touch-up and sanded through the panels paint. If that's the case you'll need to repaint.



Expensive lesson to be learned here.
 
Looks like you took her all the way down to the primer. You will need to have the hood repainted. Continuing to sand or polish at this point will only do more damage.
 
Well I was attempting to follow the guide on here written by Picus. When he was done wetsanding it appeared that the paint was ruined and it buffed out. I didnt think that I was going too hard but what do I know. So is it a definite through the clear? I didnt see any white on the paper besides what was coming from the chip.
 
Correct wet-sanding takes a lot of experience and practice to perfect. This statement is not meant to question anything related to your detailing or paint re- finishing abilities just my opinion on the risks involved



There is a good reason many of us won't post How-to articles on wet-sanding paint

 
SIP, orange pad, and a PC will not be powerful enough to remove wetsanding marks anyway.



That is definitely through the paint, time to take it to a body shop.
 
For future reference - IMHO it's better to get a sword paintbrush - a pinstriping brush and just lay the paint into the scratch and leave it. I usually thin the touch up paint with about 20% more thinner to make it really wet then hit the scratch and let it dry down to even with the top surface. Lacquer tends to bubble under the top skin and sanding just reveals the bubbles so you have to go over it again anyway.



When something has to be done to a higher level than that I use two part paint - catalyzed and do the touch up then cut the excess off with a razor blade and polish. I don't wetsand touch ups because in order to hit just the touch up paint and not have the sandpaper bend around take too much off near the scratch you'd have to use a very hard block which would change the texture - orange peel - of the area and make it as visible as the scratch.

Is the entire hood going to need resprayed ? I appreciate the advice guys. Hope the lesson isn't gonna cost too much haha
 
The hood will definitely need to be repainted to fix it correctly. Hard to tell, but if its metallic black, adjacent panels may need blending as well, depends on your painter though. It is going to cost quite a bit to do it right.
 
sfa500- That might be tricky to match...white's always tough and so are metallics. Let's hope your painter is good and that all goes well.
 
any good painter should be able to do that without any blending. Dust in that spot and reclar the enire panel. Very simple fix.

Around here good painters can be hard to find!



But yeah...thinking about it, they just re-basecoated a small area on my '93 Audi and then cleared the whole panel, and it turned out great. That was a dark blue metallic pearl that I sure didn't expect to match all that well.
