I am planning on painting the hood of my car. I was told by someone that I needed to wet sand my hood before I paint it. Would something like this work?

Why are you painting your hood?

 

wow... never seen a auto wet sanding block.LOL i always just use a bucket and sanding block and paper.

and YES you need to scuff up the whole thing that your painting!
to see if youve sanded enough, wipe the area off and dry it quickly.... and if you see shiny spots then keep sanding! if you dont the paint wont stick there and very posible the paint will flake off eventualy on that spot!
the whole thing s hould look completely dull. and clean the whole hood really good with some cleaner before you paint.

 

you dont need to WET sand before painting but you do need to SAND before painting. Wetsanding is mainly for after paint to get rid of dirt and "orange peel"

 

i always wet sand... dry sanding cloggs up the sandpaper way to fast!!!!
i only dry sand bondo areas myself for obvious reasons.

 

well everyone has their own way but me if I'm just scuffing up an area to throw a coat of paint on nothing major I'll just throw some 400 grit on my air block and go to town

 

400grit.... id use 600grit before paint! 400 is still alittle ruff and can show scratches.

 

i wetsand my car with 800 grit before repainting...it took more time but i was sure that there where no scratches because of the sandpaper....

 

yeah im with Civic Maniac.. id use 800 grit.. to be on the safer side.. 600-800 prefrence.

 

Of course it was an advise from a professional painter : )
