How to repair a dent on body

Hi guys

When I bought my secondhand 2004 MC, it came with a little dent on the body (passenger side near the rear wheel trim, it's not on the door). The dent appears to be caused by someone carelessly open their door and hit the side of the MC.

I've had my MC for almost 7 years now and I'm only just finally thinking about fixing the dent.

I have bought touch up paint and tried to touch it up and wet-sand it back. What I have done is pretty much applied touch up paint and then wet-sand it back. But I didn't realise I've wet-sanded the area surrounding the dent. I think I have actually made it kinda worse, to my opinion.

Picture below is what it looks like, on LHS shows the faded body paint from my poor wet-sand job and on RHS is a close up of it.



Does anyone have any suggestion how I can fix this? Or would it be easier if I just get a smash repairer to fix just that section of the body?

The damage is down to the metal...

Wet sanding at home is extremely dangerous as the end result is unsatisfactory 80% of the time.

Grab yourself touch-up paint and touch-up paint dissolving solvent. Layer the touch-up paint above the surface of the damage area and wait.............................................. ..............until its dried. Use the solvent to ''sand down'' until equal consistency between both good and damage area.

Hello,

Try to go to your mini dealer and ask to buy the exact same paint as your car and it come with varnish (maybe you already have that).

Apply some paint, let dry, then apply varnish. When everything is dry, wet sand every thing with a (sandpaper 1500 - 2000) to have a clean and smooth touch. With that king of paper, you will have very small scratches.

To remove that very small scratches, just buy a polish and use it until it disappear.
It would be much better..
I have done the same on mine

Thanks for this.
I read that using solvent on bodywork can be dangerous too because it might clean off the varnish which protects the body paint. Is this right?

I think I might just get a quote to see how much it would cost to repair the damage. If it's not too expensive, I might get the professional to do it. If it's too expensive, then I'll try the methods you guys have suggested.

Thanks all.

The solvent only removes the new layer of paint and it is harmless to the surrounding paint. Since the damage is down to the metal apply a putty before touch-up paint so that the paint has something to bond too.

A great trick for doing filler work is... after fairing out the filler, put a piece of wax paper over the wet filler or patch area and smooth it out,Then after about 5 minutes when the filler has solidified, (*but before the mix has completely hardened or cured), remove or gently peel off the wax paper, and it leaves a nice smooth surface with very little sanding to do. It works great !!!. large holes can be covered by putting the filler on wax paper first, then apply it to the repair area.

Well its a work of a denter to repair the dent on the body of your car.Some times the dents are minor so easily to fix them but some times the cars are crashed fully so not easy to fix them.But dent of your car are so minor so take it to repair shop.

A neighbour of mine had a smart repair done on his Honda Civic by Chipsaway, they got a small dint out of the wing caused by someone opening a car door on it and thats came out so you couldnt tell.
The colour though was a metallic black, and although the guy did a very good job you could see a difference in the finish colour where the repair was done as its a spot repair and not a whole wing respray, but if you didnt know it had been repaired you probably wouldnt notice, it cost at the time £110 and took about 2 hours at the neighbours house, quite good service I thought.
And if your cars a non metallic it would probably be easier.

I've had repairs done by dent devils and chipsaway and agree with The Nun
they are not 100% perfect as, it is near impossible to local spot repair metallic paint,
but what was done was more than acceptable, the only other way is to have the whole door sprayed which will probably involve Blending in on the front wing and rear quarter. when contacting those companies find out how much experience the person who is doing the job has, those people that have had a poor job done have probably had an inexperienced technician attend.
