Buffer, Orbital, Random, ?










Which one I buy would depend on all the vehicles and the conditions of the paints, some might need more umph than others to do the job.
I still wouldnt use pads bigger than about 6-6.5" so it would still take me a few days to properly do an F250, maybe a week if I did two-steps of compounding and then finishing.
Good luck

I wish I had pics of the black F150 before I started because a dog had jumped up on the drivers door and a trash can left a big scratch on the right side. It took time but it all came out. As mind numbing as it is slower is better. The faster rotary or aggressive pads will save time but also runs the risk of going through the paint.
My wife’s brand new Acura RDX had 2 clear coat flaws in the hood. I used 2500 paper to smooth them out and then used my polisher to polish it back to a mirror shine.
I want to get a Makita rotary but just not sure I’m comfortable enough using a rotary yet.
Glad yours is working out for you.
Flex is a world wide leader in polishers and power tools and thats just a fact-- griots is just another also ran compared to flex and rupes.
If you look @ what the big boys are using- doubt if you would find even one using a griots, and if you did the ratio would be hundreds to one

The Best of Corvette for Corvette Enthusiasts





Appreciate your help!
Got curious and grabbed a Rupes LHR15 Mk2 and did OK at first, some frustration as technique is key to Rupes effectiveness.
Curiosity reared its head again so picked up a Flex 3401 forced rotation; beast of a machine, not much technique required as it never stalls. Bit of a rough ride, after 4-5hrs you feel it, especially with a 6.5" pad. Using the Flex is like kicking the door down to get in a room, Rupes is like picking the lock; either way gets ya in the room, just different techniques...and after effects.
Spent some time with some pros who showed me a few Rupes tricks and haven't picked up the Flex since.
Also grabbed a Griots BOSS21 as i was doing a lot of large, flat panel vehicles which are tailor made for a 21mm throw machine like the BOSS21; it's been a great machine for me in those situations.
For me, the Rupes 15 is preferred; smooth and effective once you get the hang of it. Lotsa Chinese knock-offs of the Rupes & Boss now but never tried any.
Still need a 3" machine for small spaces or at least a 3" plate for something like GG6 or G9 (I'd guess you could bolt one on a G9, dunno for sure). I'm certainly no pro, just a hobbyist.
Some notes on Rupes vs BOSS from back when i first got them: https://budgetplan1.wordpress.com/ot...ff/#BOSS_RUPES
Soak with diluted Multi x
Purple power vehicle and boat pressure wash concentrate (diluted)
Tar X soak few minutes
Carpro Iron X soak few minutes
Dry car
Clay entire car
May possibly do another quick wash after the clay
Compound pad correcting
Polish entire vehicle
Carpro reset to get rid of all residues before ceramic coating
Apply Apex details metal oxide coating (artdeshine collab)
Apply second coating
Then coating with Apex detail Rehydra sheet (sheeting topper, beading sucks)
Hopefully after all of that the car will look even better than it already does, then its on to performance upgrades!















From my experiences I suggest people think about it like this - the higher speeds on a rotary aren't "what you want to get the machine up to". Think of it instead as, "a way to save time on flat panels where you are stable on your feet and can easily keep the machine moving and under control." If you're not experienced with it or not in an absolutely stable position just keep it on low speed and be careful about edges and it will be fine. Despite having the other machines I describe below, I actually use the rotary on low speed for tight areas sometimes where the vibration of an RO doesn't let you get right up to the edge (the transition between the trunk lid and rear window on the C6, for example).I have also had a Porter Cable 7424 (also classic detailing machine) forever. Not all that effective for polishing but if you're willing to spend forever doing it, it will eventually work. It is not powerful enough for gelcoat at all. It is phenomenal for applying wax or sealant though. Much easier to get a thin coat when applying by machine.
More recently I bought a Rupes LHR 21 MKII to split the difference when I bought the Vette. It does a good job of splitting the difference. Long throw on a random orbital makes a big difference. I haven't tried it on gelcoat but found it to be both safe and reasonably fast on paint. When I got it I bought a 3" backer and pads for the porter cable to use that on small areas, which worked out well.
The Flex buffers with the forced rotation seem like a really really good idea, and I kind of wish I bought one of those instead of the Rupes. Can't comment on how they are to use, obviously.
