My Review: HD CUT vs 1000 and 1500 grit wetsand

Since it's been cold and rainy here in CT, I decided to do something a little different for my HD CUT review. I just happened to have an old Chevy S10 door sitting in my spare bedroom so I broke out some 1000 and 1500 grit paper and went to town.



I split the door into two sections, 1500 grit on the left and 1000 grit on the right. The label on the bottle says it will remove 1200 grit and finer scratches, so I wanted to push it a little. I used my PC 7424XP on speed 6 with a 6" orange HF cutting pad.



I did a 50/50 on each sanded section and worked each section the same amount of time, about 1 minute each side. The sections I were working were only about 6" x 12", so I primed the pad with about half the amount of product as suggested, about 4 drops of CUT.



On the 1500 grit side, all sanding scratches were removed, and the finish was flawless. A follow up with HD Polish did not make a noticable difference. On the 1000 grit side, all but some very minor scratching was removed in a couple spots, and that would have been removed had I just worked the section for maybe another 20 - 30 seconds.



After this test, I am sold on HD CUT! It cut just about as fast as M105 has for me in the past and removal of the residue was very easy, unlike the 105.



Here's my 1-5 ratings:



Cut 4.5 - doesn't cut quite as fast as 105, but still quite fast



Ease of use 5 - on the small sections I did, I couldn't ask for anything easier. I still have to test this on doing full panels.



Dusting 4.5 - small amount of dust, but very acceptable IMO.



Work time 5 - seems like I could have worked it much longer if needed.



Removal from surface 5 - compared to 105, it's very easy to remove.



Finish after use 5 - finish was flawless on this particular paint.



Flexibility with various machines N/A - I only have a PC, so not able to test with other machines.



Price (tbd) 4 - would give it a higher score if I could get it without paying for shipping. (Got it free for this test tho! :) )



Smell (or lack of) 4.5 - really couldn't smell anything.



Labeling 4 - a couple statements repeat on the label, other than that, very nice.



And a few pics to show the testing I did. Not the best quality because lighting was poor, very overcast outside and this was done in my kitchen.

Looks good.

Later this week, I will try it on the old SeaRay, 1989, nothing done to the gelcoat in years.

Will see how it does without sanding, etc.

Will use a rotary at about 1400 rpm and a 4 ply wool yarn pad, if it does as I hope, then a follow up with UNO and a geniune lambs wool pad.

On gelcoat, that should do it and have it ready for a wax/sealant.

Grumpy
 
Ron, I'm glad you mentioned a wool pad and rotary as I've just ordered a Dewalt rotary and wanted to double check that this compound will play nice with it and the Meg's solo wool pad.
 
Looks like I need to change the label to 1000 grit........ON CURED PAINT!!!!



Great review Rich. I'm glad you're liking HD CUT.

Maybe test how it cuts the 1000 grit scratches on some different paints first, just in case this was a bit on the soft side, but yes I was very impressed with how quickly it cut yet finished so flawlessly. Though how it did finish so flawlessly leads me to believe this paint was on the hard side. Also not original paint, it was repainted sometime in the 90's and how relatively swirl and RID free it was for it's age also has me thinking it's on the hard side considering the truck this door came off was not exactly babied.
 
Those 1000 grit sanding marks look incredibly smooth. I absolutely believe you sanded it with 1000 grit, but that looks like a finish after 3000 grit. Maybe it's the type of light source you used? Either way, I'm excited to try my sample of Cut.

I absolutely sanded it with nothing other than 1000 grit on the right side. About 90% of the surface came out exactly like the 1500 grit side in the same amount of time. What you can't see in the pics are a couple small areas that left behind some very light sanding scratches, maybe just because I didn't go over those areas as many times as the rest of it. The lighting was bad and my camera is not the best so I wasn't able to capture those spots in the pics. I was totally expecting the see the entire area still covered with those scratches, but I wiped the residue off and I was blown away that it looked the exact same as the 1500 side except those few spots. YMMV, and so may mine on other paints, but for my first time using CUT, this stuff rocks.
