I tend to agree that 80 grit is too coarse for the final sanding before
paint but something rougher than 400 is needed for an initial sanding
when youre cutting through 2-3 layers of paint, surface rust, bondo,
birdshit ,snot and the like
When my 72 got paint (shitty maaco paint FWIW) a couple of years ago i
made the mistake of only going with 400, the result was ok but my GT
finished with 600 is a lot better!
I wondered if anyone in the know could review what im doing now and let
me know if im headed for a major cock up.
At present the 69 is getting its first (dry) sanding (of all the
aforementioned substances) im using very common or garden "medium" emery
cloth from Sears which is cheap and great for this purpose - provided
there is no metalwork needed (which i cant do- i failed metalwork at
school for making a bent screwdriver) i will skim bondo and spot prime
where needed and do another medium run - then 320, then 400. with odd
spot primes as necessary - I figure to get the car fully primed
professionally (for my spraying ability - see "metalwork" above) then let
the pro sand the primer with 600 and shoot the topcoats (id be letting
him do the sanding cos i doubt he wants me sanding the thing in his shop-
plus hes only open when im at work!)
My aim is to have a decent, not concours finish - its not a ground-up
rebuild but a car that will get a lot of daily use - hence my sudden
uncertainty - hehe
