Wetsanded a few spots on paint... now dull
 
I wetsanded two rough spots on my trunk with 2000 grit where I had previously removed some strong glue and had some scratches,etc.

When its wet it looks perfect but when its dry its dull. I have a buffer so what is the best product to use after wet sanding? I need it for my wife's fender that I repaired also.

I didn't sand through the clear coat I made sure of that.

Going through the grits

What does this mean?" It's a very similar idea to 'Least aggressive first' it refers to the process of using different grit finishing papers of progressively finer grit or foam / wool pads with progressively denser pads to get a smooth finish (i.e. using finishing papers 500 grit increments will yield flatter results - 1000 > 1500 > 2000 > 2500 > 3000)

Scratches are identified by a grit number; "grit" is a reference to the number of abrasive particles per inch of finishing paper that are required to remove the scratches left by the grit scratches i.e. 2000 grit scratches are removed by using an abrasive rated at 3000 grit. You are actually replacing scratches with even finer scratches until they are invisible to the naked eye..

By going through the grits each progressive piece of grit finishing paper or pad removes the scratches from that previously used. Always start with the least abrasive combination, i.e. a machine polish and the least aggressive foam / wool pad.

If that combination doesn't remove the imperfections, using the same machine polish and change to a more aggressive pad, if the surface imperfections remain, then step-up the abrasive polish and use the least next level (abrasive)only when the paint has a consistently level, smooth, satin finish should you continue to the polishing stage.

So I picked up some 2500 and 3000 grit now what compound is best to bring back the shine??? On a different forum someone mentioned a product called finesse but if there's something better let me know.

That will happen when you wet sand. Try a medium grit compound and follow up with something lighter until it is glossy again...profit.

Sorry I meant like polishing compound or rubbing compound to bring back gloss. Something to use with my buffer

Anyone ever used a product called finesse? Or is that product from the 1800s era and probably not even made anymore. Looking for a good polishing compound I guess

I wet sanded recently with 2,500 grit and 3,000 grit. Remember, you should only see a white milky residue. There should be NO paint color on the paper or in the water. I followed it up with turtle wax polishing compound. DO NOT use rubbing compound or you will have more work to do. I polished and polished until the result was nearly as good as the part I didn't sand. Once at that point, I finished it off with carnuba wax. Here are the pics.

Wet sand. Compound. Polish. Seal.

Compounding and polishing will restore the gloss.

I personally like M105 followed by M205. But I also have 3M and its pretty good too. I still prefer the Meguirs

I did it just good enough to trade it in 4 days ago for a new 2013 4runner. Still have the 325 though. :)

DarkSyde330ci 05-05-2013 07:31 PM

Was that an x3 or x5? Toyota/Lexus are excellent vehicles I miss my old sc300

No, it was a 2006 Toyota 4runner. I traded it for a 2013 4runner.

The 2004 BMW 325i I purchased for my son. Reason why were are on this forum. Plenty we want to do to it. For now, it gets him to high school and back.


Black on Black. :)
