DW443: No Heat

Sorry...still new...



Car: 06 Lexus Black (don't know how hard the clear is)



Equipment: DW443, SIP, 106ff. Orange, white LC CCS (4" and 6.5")



Problem: No correction. On speed 6 with the DW443, SIP, 4" Orange, I can go at 1/4 inch per second and the panel won't even feel slightly warm. Im putting medium to heavy pressure on it. However, I don't think it's near the pressure required to bog it down. I have also tried reducing pressure to let it spin faster. I'm working 1'x1' sections. I can hold that blasted pad all day in one spot and not see any correction...does the DW443 normally have this problem?



Please point out anything and everything, all suggestions are appreciated.

Thanks in advance, Josh Brown.
 
I think you may have just found out how hard the clear is:) Probably need a rotary polisher to correct paint such as this.

Hi Josh- just curious how did you switch out the backing plate on the DW443 to accommodate a 4" pad? Also my DW443 seems to correct as well or better than a PC. You "may" need to step up to a stronger polish/compound (HTEC, Powergloss, Clearkote Compound) and a yellow cutting pad. The orange pads I have are for light cutting. Hope that helps!
 
I usually use the 6.5" pads. I moved to the 4" pads and the backing plate is larger than the edge of the pad, at least I'm pretty sure. I can only use it that way on flat surfaces or else the backing plate would be a wrecking ball to the side of the car. Extreme circumstances call for extreme measures. Since you use the DW443, buzz, how do it's 1-6 speeds compare to a PC's speeds? Do you run it at speed 6? thanks btw.
 
hmm, put some 6" pads on it (to be safe), then start with 2 or 3 passes at speed 4. Crank her up to speed 6 and push down enough to compress the pad a good bit. You will hear the machine struggle and the rotations drop. Do some passes at about the same speed as you were with the 4" pads. Do about 12 of these passes. Then let up on the pressure and let the machine glide across the finish about 5 times. Wipe away the polish and inspect.



BTW: Shrink your work area down to about 1X1 to test if it works. Also use a hint less polish than you were using before.
 
What model and what is the name of the paint. Black Onyx and Obsidian don't have clear coats. I think the SC might have metallic flakes, so it might have a clear coat, but not 100% sure.



Are you making your passes properly and breaking the polish down? 2x2' area, Left to Right, Up & Down passes, repeating for about 5mins. Just making sure...



You'll find that any RO will not create as much heat as a rotary, which is safe for beginners, but can get frustrating because it'll take longer to do correction.

Hi Josh- I definitely would NOT use a larger backing plate than your pad. If the BP makes contact with the car, it will severely damage your paint. The whole purpose to using a DA polisher is for "safe" polishing of paint but it will take a lot longer than one could do with a rotary. I usually spread out the polish on 2-3 and immediately bump it up to 6. You will need the higher speeds (6) when doing any paint correction.

Here are the speeds for the DW443: Electronic variable speed from 4,300-6,800 opm

and the PC7336/7424: 2,500-6,000 rpm



As you can see they are very similar with the DW443 having just a bit more speed (and power, in my opinion it's harder to bog down than the PC). I agree with the advice given above as well. Take your time and work in small areas (ex. 1' by 1') until you have achieved the correction you are looking for. As stated above if you are using too much polish or working too quickly (too large of an area, speeds too low), the abrasives in the polish may not be breaking down and you are essentially spreading around the polish and removing it before any correction has occurred. Good luck and let us know how it goes after another try. :2thumbs:
 
Thanks for all the suggestions so far guys. I have one quick question that I couldn't find by searching. I asked the dealership to fix it twice before I took it back. If they had installed swirls originally and put a clear coat over it, becuase I denied it, would the swirls be covered over (preventing correction) or would they get filled in?

Sorry for the new kid question...

Thanks in advance, Josh Brown

3.5" backing plate and a 5" pad would help...

I do not believe there are optional backing plates for this unit. I have this polisher too but have not touched it since I got a Cyclo.



I was not able to get good correction on hard paint with the dw443, but I do not have as much patience as others either
