bro

use paint stripper

then start with 400 grit then go up to 500 then to 600 then to 800 then to 900 then to 1000 then to 1100 then 1500 then 2000 (if u want it really smooth)

start with a primer
1-2 coats let it dry then sand with 900 grit wipe then primer coat again let it dry then wipe off all the remains (tack cloth comes in handy)

paint a ghost coat of ur desired colour then another ghost coat keep on going till its evenly spreaded then apply a normal coat then sand with 1000 grit wipe the remains paint one more ghost and one more normal coat then sand with 1100 grit then normal coat then 1200 grit then normal coat 1500 grit then normal coat repeat till u reach 2000 grit to get mirror shine

tips : use sanding block to sand evenly DO NOT I REPEAT DO NOT use ur hands!

lastly clear coat

then sand with 1000 grit then clear coat again repeat till u r satisfied

then let it cure for 2 days

go buy some rubbing compound n polish

start polishing! u will get a great result but it takes a lot of work and time

u dont need to sand

just a primer will do

sanding it is too much of a hassle

paint a bright color inside and dark color outside

thats the trick

interior goes like this

few layers of primer>few layers or ur desired color>1-3 layers of clear coat (buy a good clear coat u need to protect the interior from scratch coz can easily get scratched by screws and what not)
