Where can I buy this and which type if there are different ones should I buy for a small scratch I have on my bumper that I am trying to touch up???

wet sandpaper is regular sandpaper soaked in water overnight. the process of wetsanding is to use said sandpaper w/ some type of lubricant and running water. it's very easy to get carried away, so use a bit of common sense when attempting this.

uhh...no. wet sand paper can be purchased at your local auto parts store...3m or other brands that specify wet/dry. to wetsand scratches, soak for two or three minutes and wrap around a foam block and work slowly. you shouldn't use anything under 600 grit. 1000 should be o.k. for very fine scratches.

lol, holy run-on-sentence Batman!

oh, and as far as lubricant, he's kinda right. drop half a capful of dishsoap in your bucket for soaking wetsand paper.

don't put any lubricant into your water. keep your water as clean as possible. wet-sand with 1,500 grit. trsut me i work with sand papers every day =x

go to autopia.org. GREAT detailing tips and a lot on wetsanding. also, if you want some great help and great products, ask excel detail @ exceldetail.com. he's got really nice microfibers and great kits to buy.

my bf and i usually get the 1000 3m and use a large bucket like the others have suggested. after which we buff out the sanding...

btw...where are you located? my bf does some bad *** detailing...norcal

thanx for the info, and thanx for the offer but i am very far from you......NY.

I highly recommend that if you need to use 1000 grit, to follow up with 1500 grit afterwards and then buff / compound. I've never needed to use anything lower than 1500 grit for scratches.

1000 grit is way too coarse if you're going to be polishing the sanding marks by hand. You may be able to do it but it'll be a total bear. Frankly I would be surprised if 1000 grit marring came out by hand. Even a dual action polisher has a hard time with 100 grit.

First of all - are you sure you need to sand? Let's see a picture of the scratch. You might find a hand polish like ScratchX and some elbow grease does the job - if not a PC + an aggressive pad and polish will take out most anything. The only time you need to wetsand is if the scratch is very deep, in which case you're risking sanding through the clear anyway so you need to be careful.

I wetsand customer cars pretty often and I never use less than 2000 unigrit (the unigrit is the important part - unitgirt means all the particles are the same size rather than regular paper which is a mix of coarser and finer grains that average to a specific grit), and always follow up with 3000 before polishing. It makes my life a lot easier.

Just some thoughts.
