this cutting and buffing is much harder than bodywork and painting,I replaced all the rust on my 62 ford galaxie by cutting out all the rusted metal and mig welded in all new patch panels .I learned to hammer on dolly the shrink areas on the weld seams then applied a thin coat of filler. I block sanded everything out to a final320 grit I applied 3 coats of PPG wimbleton white white single stage. I hand sanded 1200 grit then 1500 and buffed with presta 2 compound with a wool pad at 1800 rpm with a Dewalt rotary buffer i cant seem to get the shine up!thanks
 
1500 is tough to buff out. you can do it with a coarse compound but you should be going finer than that. atleast 3000. i end with 5000 now and buffing is a breeze.
 
Being new to buffing go as fine as you can possibly go,, like jim says,, 3000.. It will buff really quick and you won't have to buff at top speed like I tend to do.. lol.
 
do one panel at a time untill you get the procedure/technique down
 
A lot of times i stop with 1500 and the Presta ultra cutting cream will take care of BUT the Presta #2 will do nothing but give you exercise.
ALSO most important of all is make sure you are using the right pad (cutting pad, Black if presta pad.) or here again, it will just be good exercise.
 
Another thing that often happens is that you don't get all the 1200 scratches out when you sand with 1500. It can be difficult to see and the scratches can fill with sanding residue making you think they are gone when they are not. You must make sure you get all the previous grit scratches out before going to the next step. Wiping the panel clean with Wax and Grease remover and looking across the surface before it evaporates can help you evaluate your progress. Another trick is to sand in a 45 degree angle and then reverse direction with your next grit. Once all the scratches are going the same way you know your good to go. Once you get up to 2000 it will be hard to tell either way.
 
i think all the foam pads are pretty much the same . i threw away all my wool pads. lake country does have a mess of them but many are for detail shops. i use the orange and black .
 
Shine, are the lake country pads any softer than the hex-logic pads? I am going to order more compound in the next day or so and was thinking of trying orange and black Lake country pads, but didn't know if they were as firm/stiff (however you want to word it) as the Hex-logics. Also, I seen it says they are for DA buffers, do you think I would be ok using them on my rotary buffer? Thanks

i use both . dont really notice much difference but the lake country seem a little softer. i like the hexlogic pads . i have used them for quite a while . i do like the self centering hexlogic pads a little better .
 
Ok thanks for the information. I plan to order more of the V series compounds from them and a few new pads soon. I was wondering if I should stay with the Hexlogic or get the lake country pads. I 've never had any problems with the hexlogic pads, but they seem a little firm, didn't know if they others worked better?

Thanks again
Kelly
