Any bodymen on here that can answer this, spraying the sierra and I want the finish to be second to none, its primed and all panels perfect, now usually when I'm prepping for paint I will sand to p500 and grey scratchpad, then paint, the finish is good but I was wondering if I was to sand further than that, e.g. Wet 800 grit etc, will the finish appear any better? And how far can I go with wet sanding (1500, 2000, etc) until the paint doesn't have much to grip to.
I may also add the paint will be pure white, mipa 2k so it should be good covering.

Any info is greatly appreciated.

Also I guess while I'm at it what's the best grit for flatting and polishing after paint, so I can leave a good show car finish and shine, thanks

 

we just use 500 before applying 2-3 coats of 2pack paint. and for polishing up i use 1500 wet. try getting some of 3m's new fast cut. iirc the buffer we have at work is set to 1500-2000 rpm.. i can double check that tomorrow tho..

2k soild white 400 discs will be fine ,its a good gun and set up that will get ur finish ,after paint i use 2000wet an dry an some 3m fast cut polish

 

What gun an set up do you use mate? I'm on a devilbis gti with a 1.3 tip an a 110 cap. I was using a 1.4 tip but recently changed.

 

i have a gti 1.3 110 for solids and clear 115 for basecoats but just orderd a new iwata as i fancy a change had the gti 13 years

 

i'm on the same set up for basecoats as my laquer/solid gun. does the 115 make much odd's? let me know how you get on with the new gun..

 

thanks, thats what i would have used, just keen to know what others use and if it improves finish, i didnt use any discs after primer, i used a block and p320 sheets followed by 500 sheets to be sure to have it as flat and smooth as possible

it will be a satajet 3000rp gun used for this respray, quality gun!

thanks again for the help/reassurance

 

yer although its a 105 aircap my mistake lol ,its great i find the fan patten is bigger never use out else for basecoats

 

that 3m fast cut is the dogs bollocks! buffing takes no time at all
