bumper paint removal

[clivvy]

Hi Chaps,

is there an EASY way to remove old crappy bumper paint and wax to achieve a relatively smooth surface for re painting? I was hoping to use my grinder perhaps?? :nenau

brake fluid :lol:lol:lol

Bucket, water, 800 wet and dry. If you take the paint off down to plastic you will need a plastic primer and then a normal primer to go on top of that. All depends how good and professional you want it to look.

leave it, Get it muddy and forget about it.

not remotely bothered about pro look, its an old car that I dont expect to get much for if i ever sell it (unlikely, i love it) but i just want a durable, simple smooth paint job.

can i use some sort of special disc on my grinder??

if the grinders like the one i had at jims use something else mate as you will need to fill the marks you leave before you paint it.. its hard so sand flat an a surface not flat..

dammit, good point. im just trying to avoid the repetitive scrubbing...was hoping for a very easy way to remove the paint/wax.

to remove the wax you could rub it over with some thinners on a rag, but the paint will need a lot more elbow grease - scotchbrite perhaps?

...and its a very flexible plasticky paint, not hard like the metalwork, so likely to clog quickly.

hi
we use M.E.K.
Methyl ethyl Ketone
we remove anything from plastic, is not good to breathe in, its the cleaner for plastic pipework and plastic conduit(prior to solvent welding) and can be purchased from a plumbers merchant near you.

What about a paint stripper, I know they do one for GRP boats, that doesn't affect the plastic resins.
Available from any boat chandlery.
BUT test a small patch first, just in case your plastic is different.

Body shops do this all the time, so there should be a suitable stripper available.

Failing that, and I know you like your grinder, :thumb2 but there is a circular pad made from coarse plastic mesh, that is used to remove anti fouling from GRP boats.

Something like this

But I would expect it would leave marks on the soft plastic bumper.

Rustic, thats what im talking about mate, thanks!! ill get some of those orderedif i cant find any at the motor factors. Im not bothered abotu marks, and i doubt it will leave deep gouges in the plastic, so im not too worried. the plan is to strip it, back to the faded plastic which is grey. Prime it, then paint it with UPOl black plastic paint, which is for motor trim etc...im all excited now!

cheers buddy!:thumb2

Since we all have different hobbies on this site, often solutions are available from alternative areas, glad I have been of help.
I knew they existed, it was just finding them.

Best regards, Rustic.

Ok both these Items will remove paint and are very good at it but will rip your bumper to f bits. I use them for striping paint off cars on a daily basis and wouldn't dream of using them on a bumper, If I did the painters would slap me. Even if I had to plastic weld a split bumper and repair with filler or stopper I wouldn't key it with them they are to violent as specially with an angle grinder.

How about those scotchbright pads, They come with a velcro backing for orbital sanders, welders at Keymed use then to finish after the angle grinder.

 

[clivvy]

hmm...interesting..i have a detail sander, would that work ok??i know they arent any where near as violent as a grinder...

 

[kitchenman]

nick one from under the sink to try then get the real mccoy from finishers:thumb2
