Playtime with a rotary polisher...

Yep - the kit arrived :) A set of contoured sponges of various grades and velcro backing pad for 16 quid. Initially, only the sponges arrived but the seller (fleabay) sent the backing plate next day, after a bit of a prod from yours - truely ;) Now... being the cheapass that I am, I didn't buy a £200 rotary polishing machine with variable speed etc. Instead I got hold of this... Image I won't say that this monster was any cheaper than a polisher but you know me and bargains ;) After a bit of research, I was a bit worried to find that rotary polishers work from about 800 rpm to 3000 rpm. The HILTI monstrocity runs at about 6500 rpm so I was gonna need to be careful lol. [SIZE=3]Can we please ignore the fact that I'm polishing the starlet - you wouldn't want to see me practise on the Big Sweed now would you![/SIZE] Here's how the paint looked when I started... Image So, I taped off half of the bonnet for comparison and decided to kill 2 birds with one stone and mix Zymol cleaner wax (has a mild cutting compound in it) with water in a spray bottle. That way, I could apply the compound and cool the surface at the same time. I sprayed some on, whizzed it over with the machine and didn't really notice much difference. A few more passes with increasing amounts of pressure, started to show some results. I then put some cheap Asda wax on a finer sponge and gave the area a good going - over (being careful not to get the paint too hot), I removed the tape and washed the bonnet. I taped from the left hand side of the badge and polished to the left of the tape - you can actually see the difference. Image Image Most visible in this pic... Image Image Image The missus then turned up in the Volvo and due to the detailing kit being in the back of the Sweed, a whole world of polishes and waxes opened up for me :) Into the spray bottle went a fair dollop of T-cut and, filled with confidence, I went at the whole bonnet. I managed to cover the car with spray from the foam (wings, windscreen, roof lol, it was everywhere) but it came up very nicely. I then smeared some hard-shell wax on it and went at it again with the fine foam. The result... Image Image A close-up on "super macro"... Image I'm pretty pleased with the result, it's smooth as glass and only the deepest scratches are now visible (only slightly). Time to buy up some more sponges and get busy with the rest of the car (it's former owner is coming down to see us this weekend so I'll make it look nice ;)) and then on with the Sweed. Happy days!

You can really see the difference, an excellent result. Just be sure and take your time.....not too much of your substantial weight pushing down on the rotary thank you !

That grinder is heavy enough, I got backache from trying to hold it off the bloody paint lol.

be careful martin...............it is very easy to overheat the panel and polish going at that speed...........its also easy to burn through the paint...............my advice would be .................buy a polisher and leave grinders for grinding

Fortunately, mine wasn't that bad lol. Looks like it could have done with a serious clay-ing there before you polished it mate, those ferrous partacles need to be removed prior to cleaning or they'll just expand and knacker the surface ;)

I'm well aware of the dangers ascociated with mopping at speed. Believe it or not, for my size, I can be quite gentle lol ;)

job well done but polishes are going to be allowed to breakdown properly and you might struggle to get the results you want. not all polishes are meant to be used with water. can you not fit a variable speed switch.

I remember trying a foam cutting pad in my grinder once (before I bought a proper buffer), I only got it upto half speed and the pad exploded lmfao... Thankfully it was no where near the car at the time but there was bits of foam everywhere.

I can however feather the trigger to maintain a lower speed but I found I did fine at full-chat :) [QUOTE=Tomcat;622485]I remember trying a foam cutting pad in my grinder once (before I bought a proper buffer), I only got it upto half speed and the pad exploded lmfao...
