Re: ***** Need some help/info Please! *****

o and fyi the truck has been painted for 2 weeks, i would like to order the stuff i need by tomorrow so i can finish it this weekend. is 3 weeks of dry time going to effect anything drastically?

Really depends on the paint.


On this Acura we used a high solids clear and it was some of the hardest paint I've ever laid a buffer to after it cured for 4-5 weeks.

On this Corvette I was able to remove 4000 grit sanding marks on a test panel using the DA/Surbuf/M105 with ease! ...and this car was painted 10 years ago! (I did end up using the rotary though)

Thank you, Rasky, I appreciate you backing me up in this matter.
Garrick, before you use a rotary buffer for the first time you need to practice. If you could get a junk hood with a paint still on it it'd great. Remember, circular buffer can burn through your paint very quickly, you have to keep moving it. I hope Meguiar's Asia video helped you.
Good luck !!!

No prob. There were good points brought up by both sides IMO.


There are definitely some people who feel they can cut and buff a car in less time with a DA as it definitely reduces the amount of buffing steps needed. On paint that is on the softer side I would agree to a point, but I still feel DA's are limited when it comes to removing sanding marks close to an edge.

Cheers,

A rotary will be your best bet IMO at removing 2000 grit sanding marks. If you had finished with 3000+ grit paper a DA would be a decent option. If you still want to use a DA it can be done but I'd strongly suggest using the Surbuf pads as they will be much more effective than foam...though I still think you will struggle with removing any tracers via DA.


Another major factor to concider is how long it's been since the vehicle was painted, as well as the type of clear used. This could be the deciding factor on whether or not the DA will be very effective.


EDIT: Learning how to use the rotary first would also be a wise idea too.




Hope this helps,

Rasky

Re: ***** Need some help/info Please! *****

wow, i thought this was dead. I do see alot of places that it is possible to do this with a da, however this is definitely something i'm going to be doing more than once and it would be nice to have something a little more efficient.

I was looking at a couple less expensive polishers. Some brands that offer buffers around 70-90$ include:

Neiko (1.75hp)
Steelman 97565
Amstar 3002
ATD 51011
Black and Decker wp107b
Kustom Shop.

All of them are 1000-3000 rpm except for kustom shop which is 600-3000. Anybody have info on any of these?? I know i'm probably thinking too hard but 100$ is alot of money when your going to school..
maybe i should be posting this in a new thread??

No one ever said DA's can do it all, and rotary buffers certainly have their place in polishing. However, you should be able to remove 2000 grit sanding marks with the right products and techniques with a Dual Action polisher.

It looks like we don't need rotary buffers in our lives. DAs can do it all.

Re: ***** Need some help/info Please! *****

Two compounds can remove 1200 grit sand marks or finer: M105 and M95. They both should be used with cutting pads and cutting pads are not suitable for DA polishers. Where the cutting action is gonna come from on DA?
The vehicle has been already wet sanded so to effectively remove the sanding marks rotary buffer is needed. Only direct driven machine has ability to effectively cut/ level these areas.

Wow you really need to do a little bit more research on DA polishers and pads. BTW the Flex 3401 is a direct drive DA...

I'm not going to sit here and argue any further about this. A DA, direct drive or not WILL remove the sanding marks.

garrick, please do not try a rotary on your new paint job. They are not something that you can just pick up and use without the know how. One little mistake and you will burn though the paint in no time flat.

Another pad to think about is the Surbuf pads.

Re: ***** Need some help/info Please! *****

Moving the DA very slowly with the right amount of pressure and working a small section at a time will result in the removal of 2000 grit sanding marks.

The amount of correction that can be had with UC and a W8207 pad is astonishing enough and many of the scratches it removes are deeper than 2000 grit sanding marks.

Attacking this with M105 or even M95 with a W7207 cutting pad at speed 5 or even 6 will remove these marks. Speed 6 is not recommended but in circumstances like this, it proves very useful.

Just be careful to watch the heat buildup on the cutting pad as the oscillating motion against the backing plate plus the added friction of the cutting pad against the surface can generate enough heat to actually melt the laminated backing. Just use commone sense and check the pad after each application.

Good luck with trying to remove 2000 grit sand marks with DA polisher. I spoke to Meguiar's Customer Service and they recommend 100% to go with rotary. Using DA after wet sanding is a waste of time and results won't be as good as after rotary.

Well you talked to the wrong person then because its been proven time and time again that it can be done with zero issues and excellent results.

Re: ***** Need some help/info Please! *****

And that's a real good way for him to destroy his new paint job since he doesn't have experience using a rotary.

A DA can and will remove 2000 grit sanding marks using M105.

Especially if you attached a W7207 cutting pad.
