here i have the pic of the scratch. its deep enough that i can feel my fingernail getting stuck in it when i run it over the scratch and also since the scratch has reached the metal and i was careless enough to let it sit there for a few days
it has developed some rust. any ideas on how to make it look like new without costing a fortune? thanks again.
Ok I'll first tell you about how to convert Drill to a polisher or sander. You have two options. One is, go to any hardware or power tools store and ask for 5" velcro backing plate/pad. The nut on it should be M10 (10mm in dia). If you cannot find it, then the same is available in ebay India (Here
). Next, search for suitable bolt for it and length should be atleast 2 inch. The bolt should be headless but if you cannot find such, go to a small factory and get the bolt head shaved or cut or you can do it yourself.
Now you have the pad and the bolt which can be attach to the drill. Last one to buy is the foam pad for it. Few months ago I had visited to Bosch store and they had one polishing pad but it happens to be a cutting pad. This
is one I believe. You can search for the same in local Bosch store but kindly note, its a cutting pad so it will be aggressive on paint and do not use it for polish and wax application. Also note, you should use foam pads that are atleast half a inch bigger then backing plate otherwise you may risk hitting the backing plate to the paint surface while buffing.
The second option is, you can find kit that includes all the above items (Backing pate, bolt and even pads) in ebay India. Check Here
or search for more. But the problem is, those orange pads are unknown in terms of cutting power and risk of using them is high. I wouldn't use them for car detailing anyhow.
Highly recommended pads are from Lake Country which are available in Greenz Car Care, Detailed Clean India, Ultimate Detailerz and etc. LC makes lots of pads for user requirements and for you, white or black pads work best. 5.5" CCS pads cost Rs. 920 and 4" CCS pads cost Rs. 690. Note, Cutting pads are good for DA polishers.
Since you are limited on budget, I suggest you to buy 3" backing plate (like this
) and LC CCS Black 4" Pad. Because small pads are easier to buff.
Ok lets move to the scratch that has happened to your car door. I'm sorry about that but a perfectly fix can only be done by professional car painter because its deep enough and only compound and machine cannot solve it. I cannot say whether the black line in the scratch is a primer or rust but if you see it as rust, then you should act quicky.
Here a is unprofessional solution:
1. Take a needle which is thick as the scratch and slowly scratch the line (Now after read line as scratch) to remove the rust. Only the rust and not the paint.
2. After you have removed all the rust, get a good primer and painting brush. The brush point/bristles should be same as the line or even thin. Apply two thin coats of primer (Mixed with thinner as required) into the line but don't over apply.
3. Next, let it dry for 1-2 days and see if the line is still deep. If its deep, fill it with fillers. Can be found in paint shop or buy one from com-paint website.
4. Next, wet sand the line using 2000 or more grit sand paper. Do not sand more then required.
5. Get a combination paint from car paint shop and apply two coats of it using thin pointed brush and let it cure for a month.
6. Next, buy 3m finesse it or 3m perfect it and rub the line using applicator pads till it becomes glossy and line becomes barely visible. Again don't rub more then required.
7. Finally finish off with polish and wax.
I hope this works out.
Thanks... Best Regards
