well I ordered some paint to do my windscreen panel , hopefully it’s half decent as I’m out my league here with paint and quite happily put my hands up in not having a clue , lol

So Think I’ve dropped a clanger as I thought the primer would be the adhesion coat

A good lesson I think for me , lol

Just wish to ensure I do the job properly and not have the paint peeling off in time

So without saying the obvious I assume I’ll now have to order some adhesion paint , doh

Thks as always putting up with me rambling on

But then it says this on the web site , confused ???

Bless and that’s really helpful

I’ll order a couple of cans as I’d rather use it to ensure the paint doesn’t start peeling off, plus I’ve got an upgraded front plastic bumper to do so this will at least be a good test project

So is it better to use some wet and dry between coats , adhesion, primer, final coat , sorry for the daft questions, would rather ask and get it right

Also been looking at some cleaning cloths that are supposed to be used prior to painting , as all I’ve done so far is clean it throughly with soapy water

Or would using some white spirit be ok as a pre clean plse

Thks again as always

Can't hurt to very lightly wipe over with some fine grade wet'n'dry as rattle cans rarely give a smooth finish (just try running your fingertips over the surface to try it) but I'd be very careful not to go through the layer.
May not hurt to wipe over with a small bit of meths after rubbing over to get any grease off and then avoid touch the surface.

Nice one and big thks, really do appreciate

Wet and dry grit wise wise I assume I need the finest possible, ie 7000

gstuart · Jun 4, 2019

Just taken a close up pic, can also feel it’s not smooth so I assume that will help with adhesion at first then get the primer coat smooth before the final coat is applied

No don't use sugar soap or any auld sh!te you have in the shed, youl be wanting panel wipe & tack rags to degrease & remove the contaminates.

Could use gun wash & bog roll like we done the other day

Pawl · Jun 5, 2019

Also don't use the white spirit you mentioned earlier. It doesn't fully evaporate - so will leave a residue thst will prevent paint adhesion.

Many thks , for the advice

Can’t find my masking tape now, lol

Many thks ,Am Waiting for the adhesion spray paint and wet and dry

Hope it’s ok but will post a pic up of each coat , so then at least u vastly more experienced members can have a look plse, know it might be a bit difficult to see the fine detail in pics

At the end of the day I hope it will help others as well

Thks so much once again for fantastic help

Ps, will be a good learning curve to do this panel first for when I do my other second hand front bumper

gstuart · Jun 5, 2019

This is the bumper I got from another D3 member who upgraded and was going to throw it away so I took it because it has the parking sensor and fog light holes

Seems it makes more sense as I’ve now got an air compressor and buy a small air disc sander , Something like this as I can adjust the speed and thought a small one will be better for the difficult to reach places

The air compressor did come with an air gun but wondering what’s best , spray or rattle can

What do u think please

Always so helpful getting sound advice and I really am so grateful , thank u

Spray gun details that came with the compressor

Paint spray gun This professional style spray gun has a 0.6 litre gravity fed cup and a 4 bar maximum working pressure. Fitted with a 1.5mm nozzle, the gun is ideal for spraying almost any type of conventional paint. The airflow through the air cap draws paint into the nozzle assembly, where it is atomised and sprayed forward. The spray gun requires 4.5-8CFM and air pressure of 45psi.

Compressor specs , 50 x litre

Specifications: Engine Size: 2.5 HP Power Consumption: 1.5 kW Voltage: 230 V @ 50 Hz Rated Speed: 2850 rpm Current: 7.5 A Air Displacement: 9.6 CFM Sound Level: 97dB Discharge Pressure: 115 PSI / 8 bar Restart Pressure: 70 PSI / 4.8 bar Tank Capacity: 50 litres Air Outlet:

Current front bumper just to show the difference in paint finishes

Don’t know if it would look right having it the same texture right across as the corners

Or as all the wheel arch trims are turning grey might be an ideal time to spray them all mat black to bring them back how they were from the factory , they all just unclip so very easy to remove and spray them all in one hit

Seen a few who have the gloss finish for the arches but I’m not keen on that , like them mat

Update

Hi

So after removing the wiper arms and panel , gave it a thorough cleaning , slight rub down with some wet and dry

Removed the rear heater air inlet panel, so that as I sprayed it didn’t build up as paint went through the holes

then spent some time ensuring I could hang the panel up in the open and be able to move it if it started raining

Refitted the old clips and used some 4x40 screws to make life easier hanging the panel without it touching it

First coat will be hycote adhesion promoter spray

Will put up progress reports as I move further with it

Thought it better having it’s own thread therefore easier to find

Pics are it freshly cleaned and rubbed down

gstuart · Jun 8, 2019

First coat of adhesion spray , got to wait 10-15 mins for next coat

gstuart · Jun 8, 2019

Well that’s the scuttle , heater air inlet and both A pillars done by applying the 2 x coats of adhesion spray

Next will be the grey primer

gstuart · Jun 9, 2019

Now applied 2nd coat of hycote plastic grey primer

Hopefully not everyone is bored senseless, lol

Also found using a aerosol can trigger a lot easier to use , saves ur fingers going numb

Always nice as well getting honest opinions
