half way through   :y

ok, ive grinded as hard as possible  :o :o the rust from the wheel arch... got it all back to the metal thank god and im now waiting for filler to dry so i can sand.

only problem is ive looked deep in the wheel arch and it appears to be made from rust!!!!!!!!!!!!!

ive gone as far as i dare. obviously i expect it to come back.

ill post pics in a bit  :)

Title: BANG and the rust has gone... for 5 mins (piccies)
Post by: Webby the Bear on 08 March 2011, 19:16:39
i found loads of rust which was so old it just crumbled away  :o

so i grinded it out using a new wire wheel drill bit bought from b&q for £8 (bosch):

nb, i went to halfords to have the paint mixed up, gave him my colour code and he said it was just star silver which was on the shelf. £10 saving. good start!

tried grinding rust with my cordless drill. the amount of power i needed though just drained the battery and wasnt really touching the rust..... so i employed the use of 'Mr BIG':
(http://i1086.photobucket.com/albums/j453/Webbybear/mum042.jpg)
had this hammer drill for years and its so powerful it did the job a treat  :y

(http://i1086.photobucket.com/albums/j453/Webbybear/mum049.jpg)
the great big hole you see in the pic above was where the crumbly rust was. really was bad but i knew i could fill it well so i just went for it ;)

completely covered the area with filler. i wasnt p*ssing about. i then set about sanding the area with my power sander. used really rough sand paper to start and then once id shaped i  got the real fine paper and was left with a lovely result (i think lol)
(http://i1086.photobucket.com/albums/j453/Webbybear/s001.jpg)

primer, paint and laqour later im left with the below:
(http://i1086.photobucket.com/albums/j453/Webbybear/s004.jpg)

note that folds are just masking tape and i did cover the wheels before painting. its just dust from sanding the filler  ::)

well this time its gone real well.... except it got dark so i will see the final un-taped end product tomorrow morning.

hope this helps :)

Not prepared properly mate - can see the filler and underlying paint edges (not feathered), plus you've lost the shape on bumper.  Your masking is too close to the painted area and you will now have a distinct line when you remove masking - you should really give it more space and end up with a bit of overspray which will easily polish out.

My comments are meant to be helpful mate so please don't take them the wrong way.  :y

lol of course not mate, any advice is always welcome ;)

when you say the  masking tape is to close, do you mean that i should have put the concentration of the paint on the affected area and ''blended'' it by lightly dusting the surrounding area with spray?  :) :) :) :)

For the sake of eight fixings I would slide the bumper off. :y

Webby, the bumper only takes a few minutes to remove & would have made life a LOT simpler! Unfortunately,now you've damaged the end profile & it's unlikely you will get it back the way it was  :-/ In future mate, always remove any trim etc in the 'danger zone' . As said already, not being critical, just trying to help  :y ;)

bearing in mind i have the distinct line (after removing the tape) surely i can now still feather the paint though?  :-/

Hi webby, just looking at your pics, did you use just filler in that hole or is the first fill bridge a gap(red filler with fibreglass strands in). Reason for asking is because ordinary body filler is porous so absorbs moisture , the bridge a gap is waterproof so would seal the back of the hole so preventing the bubbling up that happens after a few weeks.
As the others have said you need the masking further away from the repair and don't paint up to the tape edge, spray on the basecoat then when you apply the laquer go a little further out so that when you cut back afterwards you are only rubbing the laquer and not the base colour which will avoid the masking line thatyou have at the moment.
Really sorry if it sounds like I am going on and on but just trying to help as I used to do some of this for a job a long time ago :y

cheers mate i do appreciate all help and advice  :y :y :y

no i just used the filler throughout. that makes sense to use a non absorbant filler though so bubbles dont come through. is this something available from halfords?

cheers  :y

The numbers with isopon are p38 and p40 but I forget which number is filler and which is glass fibre reinforced filler,someone will be along in a minute who knows which number is which  ;D

On the upside webby it looks like you got all the rot this time but would have been easiest for you with bumper off as others have said :y

thanks mate  :y

tbh i had a look at it at all angles after i finished sanding and compared it to the passenger side bumper (only by eye of course) and to my eye the shape or profile looks ok to me.

ill post some pics of it in daylight from all angles to see what i mean if youd like?

thanks for all your advice though guys ;) im very much still learning about all things cars  ;D ;D ;D

Basically yes then all you've got to "remove" is a light dusting of "dry" overspray - easily done with cutting compound.

You can see the change/loss of profile on the bumper in your last 3 pics - it is very obvious.  Would be quite difficult to get back now - you would need to build back up with filler, and carefully sand back using a sanding block & wet 'n dry.

HTH


I would go over your repair using wet and dry and a sanding block until you remove all sight of the filler and the paint edge is feathered in properly, then repaint.  But thats just my opinion, although I have had a lot of experience of respraying cars using a gun/compressor and local repairs using rattle cans.

However good a sprayer you are, the final finish is only as good as the preparation.

Having seen the pics of your motor in the gallery, it would be a shame to spoil it with a poor repair.  Believe me mate as it is it will stand out like a sore thumb  ;)
