guys i stripped my car down and done minor repairs before it had a full cover of grey primmer

the paint im putting on is mg trophy blue..

it took 3 goes to get it to cover the car (doors etc are removed) it needs 8 coats of paint to cover the bloody primmer if the sun shine's on it you will still see the primmer under the paint thats why it needs so much paint

it has come up perfect

but now ive started on the doors still the same problem im putting 7 coats of paint on it and you can still see the primmer under it if i shine a l.e.d light on it, it just wont cover..

i asked for 2 pack not water base but !!!!!

it takes around 25 mins for first coat to dry

if i do the mix of 50 50 like thay say it looks like piss and is so thin its like water with blue dye in it

i left the paint on the doors for 6 days and when i rub the basecoat down its getting lumps of paint on the sand paper and it feels like there is dust on the panel like sanding grit, it also seems to be rubbing back down to the primmer very quick after putting 8 coats on

any idea ?????

have thay given me water base paint its immpossible to spray it and has wasted 4 weeks of time and money

 

base coat is mixed 50/50 plus will dry faster with heat ,and also you need a dark blue ground coat over the primer before you add the colour over as its a 3 stage colour and will never colour the primer with out the ground coat

plus defo not water base as if mixed with thinners it wouldnt work

 

as said above, you need a 'base' blue coat first to cover the primer, iirc mg trophy is a pearlescent like the imperial blue ive just sprayed my car with, it's deffo a 3 stage paint

 

thanks both i have got a base blue but was told be carefull make sure the paint is correct before you use the other blue as base because it may be a waste of time with that too..

i will give it a try i cant seem to get the flow right as it looks very dry maybe its because im covering the primmer with a pearl colour

the base blue ive got is like ford electric blue
once ive done this im doing the cossie

 

Trophy blue isn't a 3 coat colour, neither is imperial blue. (they could be in some paint manufacturers but i haven't come across it) Having said that, going over a blue base will cover quicker.

As said though if it was water base you would have found out early on. I would mix it 2:1 instead, may cover a bit better at least.

 

i was gonna say mix it 2-1 to make it a little less viscous then mix the last coat 1-1
and put a slightly dryer coat on to lay the mettalic down a little more even.

i would help you if you'd of used a tintable primer

 

massive thanks to you for that on using a tintable primmer i will ask about that next time ive been spraying for 18 years and havent come across this problem...

ive done 2-1 mix aswell and that still took 6 coats im going to give it another go monday before i say fook it and give up..

i will use an undercoat (blue) and then see what happends from there...

 

Its always been a cunt of a colour. A lot of mg colours are. They are just really transparent

 

imperial blue is a 3 stage pearl in basecoat only cheap crappy paints wount be a 3 stage iv painted both imperial blue and throphy blue a few times in 16years of painting never come across paint basecoat for these two colour that a ground coat blue isnt needed

 

No they aren't mate. Trust me. Yes they are pearls but the are not 3 stage colours. I'd happily put money on it

Edited to add: arguing about this isn't helping the chap though.

 

the one and only reason his paint will not cover the primer is he missing the second stage out THE GROUND COAT BLUE

 

I am with this man

I am a painter at a ford dealer and i have been doing it for over 10 years now and can deffo say that Trophy blue and imperial blue are pearl colours but its deffo not a 3 stage colour.

and yes it not helping the chap out at all is it.

 

What paints you been usin dingle? I've used aquamax,standox water based and now using max Meyer. None of them have had imperial blue as a 3 stage. Theyve all been pearl base oats..

 

mixing skeem was standox not water base tho standard 2k basecoat ,and we always used the blue ground coat at the dealer i worked at

 

as already said mate you could use a dark blue first, but when i paint mg trophy blue at work i always use a black base coat first and then put the blue on mate same as when i paint any blue like this colour and what base coat are you using mate ? as some are a 50:50 mix and some are 2:1 mix

 

We were never told about tint able primers or ground coats at our garage. Bein stuck in the Shetlands they just leave us to it very rarely do we get told about new products

 

i always find blues cover and look better when using a black base first

 

A blue ground coat will help. But i tend to do the same as Jamie and use a black base coat. Either way it will make it cover a bit easier. But seeing as you've already got colour on you may aswell just carry on until it's covered

 

black primer is good as well for blues

 

I used spies hecker water based at work, trophy blue ect arent 3 stage.

Could easily do a repair, prime with grey primer and would cover with 3 coast no probs

Auld

 

iv painted both of these blues an had the panel coverd with 3 coats when using a grey ground coat

 

Your thinning WATER BASED basecoat 50:50?? There's ur problem right there, nearly all waterbase bascoats are only thinned 10 to 15% MAX!!

 

Exactly what the last man said waterbase is thinned about 10% only and coverage with a top quality paint isnt always great on some colours at the correct ratio so id be almost sure thats why its taking too many coats to cover, colour primers will help but even with a grey it shouldnt be that many coats. You cant wet flat waterbase coat as it will just kind of 'wash off' due to the water your using to flat it, wet flatting isnt reccomended on anything other than flatting and polishing anymore as you can trap moisture and risk problems with humidity blisters ect, much easier and cleaner to dry flat and or d/a it, best to just wipe it off using a waterbased degreaser if youve got a problem i find

 

the op isnt using waterbase he is using 2 pack plus who uses waterbase its shiiiite lol!

 

Mate you need to find out if you have water base or solvent.

as if your thinning water base 50:50 then your pissing in the wind pal

 

i use water base all the time mark would never go bad to solvent, waterbase is great in my eyes,

 

i use water base every day at work as we have to and it is good if use correctly, but i will always use solvent base coat on my own cars while ever i can still get it as i think its better but thats just my own opinion,

 

Completely agree.. I can't stand the stuff!

 

what water base paint are you boys using ?

 

Baz, out of daftness, they havent given you basecoat already thinned have they?

 

wouldnt be the first time thats happened

 

I'm using max meyer now. Was using standox at the last place I was at.

 

i always put down the blue black tinter from my lechler scheme as a ground coat for colours like this, otherwise the coverage is just atrocious

i think if u had waterbased base coat, it would be fairly obvious, for starters if you're knocking back the basecoat as u say, the water from wet flatting would just wash the basecoat off lol. plus, he would have been sold the waterbased specific thinner, which is pretty damn obviously different to a standard 2k thinner

 

I'm pretty sure he's established he's using solvent. He was just curious as he was having issues from how i read it.

BigErn makes a good point about it maybe already being thinned.
