i just got a new door that needs to be sanded down and painted. i started the sanding part, but havent gotten too much further than that. what sandpaper should i be using? wet/dry? itll take me a week at the rate its going right now.

any tips to speed sanding the body panels or is it just going to take forever anyways?

 

after you DA sand, all the sanding will be wet sanding. use a 600 to rough it up then use a 800. make sure your always keeping it wet.

 

if there are no dents, dry sand it with 500, then seal and paint, (I hope you are using the 2 stage paint system), and then clear it. no worries! I do it every day at work

because it's tech related asshat...

now wouldnt you want to use somethign finer than 500 grit... when I was sanding my car and filling in dents I used 1000-1500 and wet sanded with a little bit of soap and water, came out flawless

 

If the paint your going to use is mat. you need to atleast use 600 wet , if not you can go with 400 .. Use a block (something flat) and make sure to keep the paper clean & wett

Paint dose not stick as well to 1000-1500 , it should be used for wet sanding out runs/trash or when you are only going to reclear/blend.. IMO

 

if your taking it to metal use a d/a with like 150...use filler on the areas that need it ...then use etch primer then color build primer then block sand with like wet 300 then 600 and then it should be smooth enough but rough enough to give the paint something to stick to. it you wet sand with like 1000 grit the paint wont stick well to the primer and will flake...wet sand 1000 and 1500 is used mostly on sanding the clear to help get rid of high and low spots and help make it look like glass after buffing.

 

i would use 320 on a DA.

 

DA? what is that exactly?

so i dry sand first, and then use a rougher wet paper after all the old paint a primer is off. is this correct? or should i just use a rough wet sand paper from the beginning?

 

Just painted my car, check it out!

Wet sanding or dry sanding is your preference when it comes to sanding the clear and base color off. I prefer wet so it doesnt get dusty and the make the sand paper last longer. If I were you I would just wet sand it using 250 Grit SP til the factory primer appears. Then fill in the deep scratches and dings with putty, or if is is too big, use bondo. Then wet sand again using 400 to 800 grit progressively till you even things out. Make sure you use a sanding block to have a flat miror like finish at the end. Then clean it very well, spray about 6 coats base color, 5 coats clear and when it dries, wet sand using 1500 grit SP then buff it!

 

A da is a type of sander(Duel Action Sander).You do not have to sand all of the Old Clear & Paint off the car (unless the part has been painted 3-4 times) , you do not have to prime the hole door . If your trying fix dents & dings Block sand the door with 180 (Keep it Flat!!!,if your not fixing dents and dings You can skip this and only wet sand) , You will notice spots that wasnt sanded is a low spot and places that brakes through to metel could be a high spot use your hand for final judgement. Fill with bondo / putty as needed. Any spots that have filler or have broken through the paint will need to be primed.Then wet sand the part as i stated above . As far as paint: 1 coat of sealer,3 coats of base, & 3 Coats of Clear anything more than that is honestly Wasted and you run the Risk of having "milkey" clear... But I only do it every day so what do i know

 

okay.. well I didnt sand to the metal... I just sanded off the clear and used the factory paint as a primer sort of ... but then I sprayed primer and then painted the car... here is one picture... turned out real good I think

He is right...You dont want more than 12mil of paint on your car...on avg the factory paint is about 4mil...

is that a booth that you made outside? If so did you get much dirt in the paint?

no I didnt make it the guy who painted my car did, he's been painting for 40+ years so he knows what he's doing... didnt get any dirt in the paint what so ever, worst thing was the drips in the clear that were all sanded out

 

any one have tips on shooting the paint on? Especially the clear or websites?
