Will tackle the job myself as i can get the paint mixed for me as i have the codes so just looking for some advice on preparation and finish
1. wash and clean area with soapy water , dry
2. use 340 sandpaper to rough the area
3. clean and mask off the surrounding area
4. apply coat of primer allow to dry 3-4 hours
5. resand with wet and dry
6. another coat of primer
7. allow to dry fully then apply first top coat
8. allow to dry and apply second final coat
9. once dry allpy clear coat
10 fully dry buff to shine

Have i covered everything , will be using aerosol cans premixed from motor factors
Any advice much appreciated

you may need to clear coat the whole bumper to blend it in if you are fussy!

When you say you're having the paint mixed, are you actually getting paint, or is it going to be a rattlecan?

Firstly, don't bother washing the bumper, there's no point.

You need to feather out the affected area so it blends smoothly with the original paint, but here you might come into a problem. If a powerwasher has lifted some of it, you'll probably have loose paint on a significant portion of the bumper, and you'll end up chasing it with the sandpaper until you can find some properly applied paint.

There's no need to wait for primer to dry 3-4 hours, and there's no need for multiple coats. You need to get the area smooth with sanding/filling before you apply any primer. Something like U-Pol's Hi 5 primer would be ideal for what you want, it's normally a beige colour which is neutral enough for painting, and is air dry in about 5 minutes. Sand that smooth with 800 wet and dry, and plenty of soapy water.

After that, you should get a scotch pad, some anti-sil, and scour the entire bumper surface using the anti-sil to remove any contaminants/tar - this is why you don't wash the bumper as you'd be taking this step anyway.

You'll need to paint a larger area of the bumper than just the repair section to blend it in, and with a light colour, you'll end up applying a few coats to get good coverage. Once that's dry, you should really lacquer the entire bumper for a consistent finish. Again, if you're using clear coat from an aerosol, you'll find it hard to get a good finish.

If you've got the skill level to pull this off, then fair play, but since the kick off of the recession, I'm seeing more and more modern cars on the road with hand painted bumpers which look terrible. What's worse again is that Halfords Cork were giving ridiculous advice the last time I was in to a guy who clearly said he just had a few light scratches in his clear coat (Which would probably buff out) - the teenager working there convinced him he needed an aerosol of paint, and went about telling him how to apply it in the most wrong way possible. I guess what I'm saying, is that if you haven't done this before, you're as well off just dropping the car to a bodyshop to get it done. You're going to end up spending a minimum of 50/60 on materials alone, and a lot of time.

yeah its a small enough patch on the bottom side end of the bumper so not that noticeable if there are small blemish in the finish

have attached a photo of the damage , local bodyshop want 350 for full respray
i know i can match the exact toyota colour codes and use a good primer , will need to sand it back beyond damaged area and build up the primer layers and top coat

Which is an average price.

You do know a colour code is only a starting point in finding the correct colour, right? I mean 1C0 which is Toyota Platinum has about 16-19 different variations which are all completely different when painted, but all use the same colour code?

As I said previously, and as your photo has backed up, the paint that's on there has been badly applied, and will mostly likely keep flaking off further and further. It looks as if the bumper has been painted directly onto the plastic with no primer at all. You're going to be chasing back loose paint across the whole bumper, and even if you're lucky enough to be able to feather that area, the next power wash will take off another area of paint.

Yeah I know , its toyota 040 superwhite 2 , yeah i know i might end up chasing the flaking paint back but with any luck can contain it to bottom half of the bumper and will have to be careful not to powerwash that section of the car in future

Owen

I dunno, if it was me, and I wasn't able to paint bumpers for a living, I'd be inclined just to drop it in somewhere and get it done properly and not have to worry about which area of my car I can/can't wash in the future.

hey i know what you are saying but i dont have 350 euro to spare right before christmas

I got my front bumper done for 280 EUR in Dublin 8. I had the same problem - paint flaking off during powerwash. They had to sand and re-spray the entire bumper. I'm glad I got pros to do it because they did a super job and no more problems with powerwashes.

PM me if you need the name and number.

I know money is tight at the moment for all at the mo. ‘Paint doctor’ is right it looks like a poorly painted bumper and that blowing in a corner will only partly solve the problem.
€ 350 aint bad for a full respray – sand down & remove existing paint / prime / paint and then lacquer - it aint money for jam for a body shop. The best thing is that you will have a warranty – if you go to a proper body-shop (and not yer man with a shed who’ll do if cheap for cash!!)
If you approach them and seriously want to book the car in for the Job they would be foolish to refuse to maybe do it for maybe €320 if it means actually getting the work (I’m sure they get dreamers asking for quotes every day, that said don’t go taking the Michael by offering them say € 250 -they won’t work a negative margin)
It is of course a month to crimbo.
2 temp solutions
Power- wash the rest of the paint of the bumper. The car will be 2 tone but at least it won’t have a flaky paint look.
Or as some of the drift/JDM boys do stick some tuner brand stickers over the flaky patch
Final solution
Save up a few quid per week in the New Year and by February you should have enough to get it done in the body shop
Your OP is about a DIY job - no offence to your good self but using rattle cans is a bodge - i know Ed. China does on 'Wheeler Dealers' and as much as I enjoy that show that element of the show is a load of codswallop !!!

Got my rear bumper done for 180 and my front for 200 in a cork bodyshop. It's bloody top class work! Power washed it at the weekend no bothers.

My local guy just painted my Front bumper complete for €150 so whoever is charging 350 is raping you!
