Machine polishing

[McAuslane450]

I’ve just invested in a dual-action polisher. Seeking advice about how to safely use it, as very wary of causing damage. I understand different compounds require different pads? Meguiars and AutoGlym have always been my products of choice, but interested to hear of experience with other brands. Thanks in advance.

You are likely to get more responses in the bodywork and detailing section. If you would like me to move this thread then drop me a message.

I have used Scholl Concepts S20 Black on my Griff and achieved great results. I used this with Orange Hexlogic pads. Stay clear of AG and Megs. There is a lot better products out there. Go on Forensic Detailing You tube channel. He has a beginners guide to DA polishing. Very good channel.

I wouldnt worry too much about causing damage as it's a DA polisher. It will likely stall out (the rotations) before you can do any damage (and only oscillate). They are much more forgiving than a rotary polisher.

As for compounds, there are plenty to choose from. Koch Chemie, Rupes, Scholl, Menzerna all make good compounds. Having said that, and if it were me just starting out, I'd pick up a bottle of Meguiars Ultimate Compound. It's pretty cheap, gives good results and is easy to work.

Pads are just as important as the compounds. Flex and Rupes both make good pads in various sizes. Slightly cheaper are Chemical Guys hexlogic pads, which give good results.

As stated above, with a modern DA polisher you shouldn't run into any problems. They are very safe to use and unless you're actively trying to do damage you'll be ok.

Only major thing to remember is a TVR will behave differently in regards to heat. GRP won't dissipate it even remotely close to as well as a metal bodied car. Keep the polisher moving at all times and you'll be fine.

This is purely my personal opinion and I am most certainly not trying to start any sort of debate in that manner. But for me I'd forget checking out the YouTube cannel mentioned previously. Most of it is misleading and a decent part is pure nonsense...
I'd look up AMMO NYC run by a guy called Larry (the YouTube channel in particular). He details some of most expensive and rarest cars there are, everything from modern Veyrons to 1960's Ferraris. He knows what he's talking about.

As for products pretty much any of the major advertised brands will be fine. I agree to probably stay away from Autoglym and if you go with Meguiars then buy from their Professional range rather than the Enthusiast. Lots of the worlds top pros still use Megs so there is nothing wrong with their stuff at all (again though the Pro range NOT the Enthusiast stuff).

I've polished dozens of cars and the TVR many times. Just give it a go and don't overthink it.

As mentioned above Scholl S20 black and an orange hex logic pad will give great results.
It’s very difficult to damage paint with a DA but just keep the machine moving slowly.

Technic is vital too.

Long old video but very useful.

It’s actually quite therapeutic, plus does a great job. I use just two processes, as I get bored easily…. Five minutes with a cutting compound, then less with a polishing compound. Pads can be bought with compounds in a kit. Get the polish on slowly, then spin up to 60 to 70%. Keep moving slowly and methodically keeping the sponge rotating, light pressure. Repeat steps if not happy.

There are super polishes, if you really want. Then a coating, ceramic or whatever you choose.

Have fun, keep the mains cable clear of the body, it marks.

Thanks so much everyone! All the advice very much much appreciated and given the confidence to give it a go, without the need to worry too much about finding my way to the glass-fibre! Thanks for the product advice, interesting to read views on the usual (AutoGlym / Meguiars) suspects. Will certainly take some time to have a look at all those others that have been listed. Looking forward to having a go! Thanks again!

Just bought a DA one myself - interesting choices of brands (and opinions) from PHers …

Life’s too short for 3 stage amateur detailing, I use an all-in-one called Rupes Uno Protect.

I can do my lwb VW van in less than 2 hours start to finish with a light polishing pad and some good quality Korean towels.

I’ve got a Makita cordless da and run it at around 65% speed and frequently check my work.

My paint looks incredible for a 5 year old commercial vehicle, I often get asked how I make it so shiny.

Also a huge fan of Gyeon Wet Coat
