Long story short had someone shoot the camaro and the paint job is wavy/ripples all over the place. I asked the painter how he wet sanded the car because it was straight after we blocked/guide coated the car. He then shows me on a piece of scrap metal. 3m paper and his hand... no block just his finger tips!

Would/could this be the culprit of my new rippled torch red front panels? I have always been told to NEVER block by hand, always use a sanding block etc... hence its called blocking.

I am contiplating whipping out the DA and some 2k mirka and try to smooth out the clear some and rebuff it. Think that will work? The panels were heavy coated with clear. he had puddles of clear on the floor in some spots the size of a quarter and thicker than 2. lol

my guess is you'll be re-blocking and painting the car. I would try blocking it but most likely you'll go through the clear before you get it flat.

Yes, you should use a block of some sort for sanding by hand.

do you see runs in the clear? could just be he smoothed out the runs in it but didnt make them perfectly flat. try and block the clear, and if you go through, well you were headed that way anyway. i cant believe its that heavy that it was laying on the floor!

NO DA!!!!!!!!!!!!!!! If you have that much clear on the car start with 800 - 1000-1500 and finish up with at least 2000...

I am going to give blocking it a try starting with 1k and work up to 2k then try buffing it out. I had another painter come by and give me his opinion. He said the same thing you guys did; looks like the guy worked the runs and trash etc... but did not "block it" he just smoothed the paint out.

Like you guys said no hurt in trying to block it and if I start burning thru then cross that bridge if I get there.

Listen to Mario! Start with 800!!!!! If it is truely as wavy as you say, you need to use the correct paper (tool) to cut it down flat. If you start with too high a grade of paper you will be waisting your time and never get it flat enough! That's what my previous painter did....twice....on my car! He was so proud that he started blocking with 1k (or 1200?) and went to 3k...problem is the paint was never flattened out before he worked on the scratches and made it shinny....not to mention a few other issues....but that's a whole nother show!!

Get some wax and grease remover to "wet-check" your progress.... block a portion of a panel, wipe it down, squeegee it off... then wet it with the mild solvent ( Naptha works great... Tractor supply or wallmart, almost any hardware store) and stand back at a 3/4 angle and sight the panel looking for waves. The solvent is much thinner than water, which creates a surface tension and can fool you a little when trying to find heavy spots that used to be runs.... Chances are you're going to burn through... regardless you need to block out all the inconsistencies before a re-shoot anyway. Sorry for your trouble... I've seen that a bunch of times; painter is gun happy and overcoats everything thinking "It'll Buff Out".... Sometimes it's hard to fix things after the fact... This exact scenario is why I spend so much time coaching guys to "do it themselves".... If ya want it done right...you know the rest.

Good luck!
