I am interested in either a new front bumper at right price or could do with some advice on bumper prep, i understand you have to smooth and can sand them - but what to use on scratches/scuffs (special plastic bodyfiller - any recommendations?) and what primer do people use on bumpers?

Cheers Whiteee...

ps. sorry to post this thread if it has been asked before (and i did ask in another thread) but struggling on finding information on this even using search!

When i use search i cant select categories lik just customising and modding - any ideas?

bumper painting and smoothing

hi ive just recently been doing my bumpers


1st step cleaning


first thing to do is to make sure you clean your bumpers very well

products like silicon that are in back to black are the main reason why paint flakes off.

give it a good scrub with a brillo pad.

dont worry about scratching surface if anything its good too.

then panel wipe / degreaser again and again and again.

then sand the bumpers for a good key.



2nd step priming


after you have sanded for a key

panel wipe again

use an adhesion promoter like UPOL.

leave for 20mins then a good couple of coats of plastic primer.


3rd step primer filler


once plastic primer has gone off usually 2 hours at least

then spray with primer filler.

keep spraying coat after coat after coat.

you need enough to fill dimples in bumper plus a bit more for smoothing

then let this dry fully

usually use about 3-4 rattle cans per bumper depending on sizes used


4th step sanding


once filler dried use 800 wet dry sandpaper

use it dry and sand and sand and sand and sand.

will go through a lot of sandpaper but will eventually get a very smooth finish.


5th step painting.


before painting use a tack rag to ensure all dust and particles are removed from bumper

prime in whatever colour needed for your paint

then paint

if you make errors, runs or get orange peel with paint dont worry just let dry and get the 800 wet dry and use wet to sand back to a flat surface again ready for next coat.

dont get too stressed about painting as you can always sand back and just try again.

give the whole bumper a good sand with wet dry before your final coat to ensure everything will be as smooth as possible.


6 th step lacquer

the final coats!!

spray on evenly in at least 4 coats

same principle as paint sand if you make and error

then flat back again before final coat.

bumper should be nice and shiny now.

leave for a good few days to go hard.

then use a very high grade sand paper at least 2000 wet dry if not higher

go over whole bumper

then use cutting compound such as g3 and polish up bumpers until shiny again.



stand back and admire should be able to see yourself nice and clearly in them

only problem is i am waiting now to give the van a going over with g3 before i fit them as im worried bumpers are shinier than the vanT:

I'm thinking of doing this, so an easy to follow "how to" guide is great stuff...

Is it possible to make a good job of it with spray cans ?

I imagine it's all in the prep work, and then the sanding and finishing?

Any pictures fella? Sounds like you have adopted the 'If a job's worth doing...' approach! Very thorough.

Cheers,
Paul
