if u really want to save your self $$$ and want a good job then just strip it and nothing ells. i am a panel beater if u go and sand the paint and take off the shine the beater wont be able to see any small dents and riples. that means when the painter primes the car and rubs it back if he finds dents they then have to fix them and re prime them makeing more work and adding to the price. and if they dont find them u will see them when the car is painted then its too late. small dents fine dents and riples can some times be really hard to feel but in the rite light you can see them but if u sand the paint you wont see them and make it hard to feel them. so if you want a good job dont touch the paint work let the panel beater do it.
