i have an electric bluepoint buffer with 7 inch yellow disc i have an old bonnet i can have a play with could someone please explain whats the best way to use anelectric buffer, why does it have two speeds
does it sit flat on the surface being polished do you use left and right motion how much pressure needs to be applied and when buffing edges is it best to do these by hand
is g3 the best stuff to use and are buffers used only for cutting back lacquer or can they also be used for polishing
You need different heads ideally. A hard one for cutting and a soft one for polishing.
I would use the low speed with G3 to avoid over heating the paint and a higher speed with a finishing polish such as G10.

cheers mike what is the yellow head is it soft or hard and any particular method of using do i apply very light presure
does the g3 take back a layer of lacquer and then g10 applied as a polish
I've no idea. The yellow one is probably a hard one but I can't be sure. Basically, hard is hard and soft is soft!!!
G3 is a course ish cutting compound (well, it's pretty fine really) and G10 is a finishing polish that will take off just a very small amount of laquer (basically to get rid of the scratches left by the G3).
There shouldn't be any need to use too much force, and be very careful not to get the paint too hot (much the buffer around the panel a lot).

Iv'e used t-cut with mine before. When i bought the car, the paint was badly faded, but after a few runs with the buffer, it was restored.
There are usually two heads. One is like a towelling type, use that for your cutting compound (remember to wet it first so it damp, and spreat the compuond around with your hand to coeat it evenly). Remember to keep the head moving and let the machine do the work, so dont apply pressure.
The second one is the polishin bonnet, wich is woolen. Use this to buff up the shine after polishing and get rid of any streaks etc.
Iv'e use mine like this several times and the finish is awesome

I used to be a sprayer.. you should have 2 mop heads.. one is quite hard to touch this is used with little to no pressure with G3 must be kept wet.. this is a cutting compound that takes layers off.. so if you leave it in one place or catch the edge of bonnet etc you will take the paint off and probably end up down to primer or even bare metal.. you just have to be very careful on the edges. for example if you have the polisher handle in your right hand and the other bit in your left hand it should spin clockwise.. so on an edge you need to turn the polisher and tilt it so you are polishing away from the edge not cutting into it.. if that makes sense LOL...
The second mop is very soft and usually looks like bart simpsons hair lol this is used with a finishing compound to remove hairline scratches left by the G3 etc..
hope this helps
Back when i used to work in bodyshop when using the mop and compound we used to geth the mob head be it cloth or sponge a bit damp so that it didnt burn the paint whilst applying.
Worked all the time

cheers lads been most helpful will try on an old bonnet first do i always use the low speed nutsaboutastras couls you please explain your theory it seems very important
im right handed so will have handle in my left and holding buffer in right what do you mean by turning the buffer, the buffer i have purchased is a bluepoint is this any good it has two speed and comes witha yellow head do i just wet this well and apply g3 with cloth to panel and then buff do i then need a new mop for g10. once g10 has been used do i apply a polish like autoglym by hand or again use the buffer
Ideally you want a soft mop head for applying the G10. The G10 is a finishing polish. After the G10 apply a WAX by hand. I can recommend Meguires Gold Class wax, but there are plenty of others.
Personally I apply a smal amount of G3/G10 to the mop head, smear it on the panel and then turn the buffer on to polish.
Mike
Yeah, what they said.

At first i would use the slow speed just to get used to it.. you will need a softer mop head for the G10. by polishing away from the edge you will avoid cutting into the paint.. eg if the whole bonnet is to your left and you are polishing the right edge stand at front of bonnet and tip polisher forward and to the left a little.. if you see what i mean.. if you do it the other way eg bottom and right the polisher as it spins clockwise will try and cut into the bonnet!! where you from if your near i might be able to come and show you...
i think i know what you mean
got my buffer today now the guy whohad it was t cutting directly from the sponge is this how it is done or do you put a cover on the mop first he also decided to cut the top layer of the sponge as it was dirty and guess what he didnt cut it even so do i need to but a new sponge/mop
could someone please explain what different types of sponges there are and what each one is used for
www.bodyshopwarehouse.com
They sell all the white/blue/pink etc heads and tell you which paint types and jobs they are for.
Delivery is a flat £10 from them (from memory) so after you know what you want, get it off eBay, there is a guy who does 2 heads for under a tenner delivered, I'll find an ad....
http://stores.ebay.co.uk/Belair-Supp...d-Collectables
Type in "sponge" in the search box, it'll bring them all up (scroll to the bottom)
He also does G3 and G10, but if you are buying that too, go to Bodyshopwarehouse as the savings will more than pay for the carriage.
For reference when the eBay url dies off...
Blue: soft open sponge for compounding/polishing cellulose & acrylics.
Red: very soft sponge for final finishing and polishing.
White: soft polishing & buffing sponge. Use for compounding 2-pack paint systems. Excellent results with G3 paste.

cheers so you just polish directly using the sponge and no covers i have a white one on at the moment is that ok for the g3 and ill polish by hand until i can get the correct head for polishing
is it best to just apply the g3 all over the panel then wet the sponge and keep buffing until all the g3 comes off
i did have a go today come out good without wetting the sponge but as the g3 dried the sponge kept bouncing back off the panel as it kept gripping the panel
is it best to go across the panel holding it for a few seconds or beat to keep passing the buffer left to right. i also found if using it flat the buffer would grip the panel and bunce of the panel but i dont know whether this was due to someone having cut the surface of the sponge making it uneven
on a new pad keep it wet to reduce chance of burning paint plus if dry buffing the resistance makes a shine alot easier but it isnt true and the next day u will see the faded part or the flatted part etc. always keep it wet till u get a nice shine. do this twice then wet ur compound clothe and go over it again until dry. just be careful of the edges. if ur worried put masking tape over adjacent panel edges. after this then machine glaze the panels with the softer dimply pad... hope this helps...
Just ripped this off a Mark Evans DVD.
Its just a short example of how he polished his seat on the trike. 2000 w&d and G3 too on a polisher.
