REPAIR Random Orbital Polisher?

alright so i moved into my house in 08 and the guy before us had left a bunch of random stuff in this ratty old shed out back. my family and i very rarely use the shed but i was in it today and found that the guy had left a black and decker 6in random orbital polisher model bp900. i decided to clean it up a little bit than see if it works. i dont know much about polishers but it spins fine no weird noises shorts or anything. seems to be in fine condition. do any of you know of this model? would it work well to use on the car? and any products you suggest i use? it was in the original box and also included a never opened foam pad with 2 unused terry cloth covers and one foam cover. so i dont plan on using the ones that were already on it with not knowing where theyve been but instead the brand new ones. as for info on it idk what would be good info but the only thing online i could find was it for sale on ebay here Black & Decker RANDOM ORBIT POLISHER BP900 NEW IN BOX (028873000903) | eBay

the only problem i forsee is that it only has 1 speed?

here are specs that i found on the unit and box (if useful?)
bp900 type 1 120v .5A 4000 OPM double insulated
 


4,000 OPM's not too bad. Think I polish at like 6,000 OPM and wax at 3,000 or something like that. Not hard to find 6" bonnets either. Probably the kind of thing I'd mostly use with a wax/polish combo product.
 
4000 opm with no variable speed adjustments = useless with any type of polishers............
 
trust me save up some more and get a porter cable, thing works like magic. and you can't F up your paint with it.


before porter cable buffer job.

why thank you sir.

ask danielle, its a work out, your arms will hurt for days after, they dont really start to hurt till you are 1/2 way done doing the car, but at that point you cant quit, because its instant gratification lol

and just a reminder, that buff job is only 1 cut, and wax. if i were to do 2 more passes around the car with finer and finer compounds, it would look like real glass, deep and shiny.
 


I agree with Scotty save up the money and get the porter cable. With no adjustable speed or a vented disk, you really run the risk of burning the paint IMO.
 
The porter-cable is great, and it's definitely a good detailers starting point. I've pretty much maximized what I can do with mine, so I'm upgrading to a rotary polisher..... A lot of people are scared of them, but with patience, it will give the BEST results.
 
It can't hurt to use. I would mainly use it as a spreader for my wax. It will take some of the elbow grease out of it ;)
 
Scotty...if you are hurting after using a PC7242 then you are doing something very wrong. There should be nothing more than holding and guiding that baby over the car. It's time, not effort. :th_winking:

Adjustable speed won't keep you from burning paint. Using low grit keeps you from burning paint. With any standard polish/wax, there's no way you can burn paint. His junk polisher will still put wax on a car ten times better than a normal buffer and a hundred times better than hands. The human matters more than the machine [read: technique and patience]. And the car needs wax.

my paint was really fadded out, and i was leaning on it with more than firm pressure. and both my shoulders are F 'ed u, so yeah i was sore for about 3 days. and lets not forget how much it vibrates, my hands and for arms were going numb. and doing the side of the car are no fun.

True it takes technique and patience and yes vehicle paint needs wax. Not arguing with you there.

so what would be the best use for this machine?

use it to make your cars paint shine like the dealer never saw it shine. after i tinted my tails i used it to buff the clear coat on them as well.

but really the whole set up with pads the pc and good wax and compounds and swirl remover and your looking at maybe 300 bucks or more. unless you find a used porter cable for cheep. the results tho, man you'll never wax a car by hand again.
 


Polish, then wax. Or wax/polish combo. Or sanding the deck. Don't let us PC enthusiasts slow you down. The machine will do the job.
 
you can try it out, just dont use in in one area to long, follow the vid i just posted and use it like that, but do keep it moving, dont let it sit still like the porter cable can, your paint will burn off.


is this the tie on bonnet type buffer? if so maybe you could get some Velcro and stick it to the base if it so you can use a real pad, they all have velcro on the back to hold it to the buffer.

post a pic of what your working with. or web site link to it.
