Evening all paint gurus, your comments would be appreciated

I have a mini 30 in Cherry Red - basecoat & laquer, the car in areas is showing the laquer peeling off and the basecoat looking like a teenagers complexion. So I have sanded down the offending panels, gone through the laquer / basecoat and yellow primer where the basecoat is at its worst. So therefore I reckon all these panels have been painted before as I do not believe the factory used yellow undercoat / primer. The areas that were really horrible have been taken back to bare metal. Currently the car is sanded down using 240 grit sanding pads on a Bosch orbital sander.

Is it OK now to hit the panels with 2K primer, how long do I leave that before I sand it. Do you sand primer wet or dry by the way?

I have been told Perlescent Cherry Red is very watery and covers badly, so I have been sold some flame red undercoat, again 2K, does that just need to go matt before I hit it with the basecoat or do I leave that to dry overnight? .... Or is that red undercoat a bad idea?

How may coats of basecoat is recommended ?

Then apparently I allow the basecoat to go matt, then I go at it with the 2K laquer, around three coats at 10/15 minute intervals.

I do have an air fed mask & a space heater in my garage.

Is this project feasible or am I wasting money on the material, or would I be better passing the job onto a professional sprayer?


Any guidance would be greatly appreciated

2K primer best left overnight if you dont have a lowbake booth
you can wet flat if you wish(800 w&d) but the trend now is dry flating (400 orbital sander)
the solid red base is a good idea if the colour you are using is poor at covering BUT you still have to cover with the cherry , what may happen is you think it is covered but what you may end up with is your base red with a translusent coat of cherry over and this will be a differant colour
base coat MUST be laquered within about 20 mins or the laquer wil not bond properly to the base and will peel .
no need to wait 10/15 mins between laquer coats , it just needs to "flash" off (poke your finger on the masking close to the edge )

Hi Woody

Thank you, it appears I am not a million miles off the mark

I think I will do the primer today, & leave that 24 hours and dry sand that as you suggested.

Just to clarify the undercoat / cherry red base coat and the laquer all gets applied at 5ish minute intervals

How I love cellulose!!!

UPDATE!

Two coats of primer later and its looking good!


Next problem .. getting the paint to match. any suggestions again would be gratefully recieved!!!!

Blow it into the panel next to it ,
basicaly you get good coverage of basecoat at the end of the panel next to the fresh painted panel and fade the new paint gradualy away to the other end of the panel and then laquer the whole panel

[Senile Old Git]

woody, again thanks


So a flat down to the adjacent panels to take the gloss off the laquer, then follow your instructions.

As today is a day of rest (so I have been instructed by her who is to be obeyed), I will flat the primer tomorrow, I had this idea of getting some 2" squares of metal, give them the red undercoat treatment, then base coat, but each square being given varying coats of basecoat to see what gives me the nearest match after all have been laquered.

Is it true the more coats of base coat the darker the end result will be ?

[Senile Old Git]

can I be so rude as to say "BUMP"


because I am in desperate need of Woody's response ....... I thank you, one and all

[Woody]

the colour only gets darker if you are painting over a lighter primer , and then it only gets darker untill the corect coverage is achived .
what you need to rub down the adjacent panels is "GREY SCOTCHY"
(this is made in differant grades and colour coded, from 3Ms is is called scotchbrite)
if you use wet and dry the flating scratches will be visable after the laquer on the part of the panel that gets no basecoat

what an eventful day!!


Dry flatted the primer, then cleaned the panels off, Started spraying the undercoat & the fish eyes appeared on impact.

So all stand down, wet flatted and cleaned all panels again, this time a really light guide coat and all looked well. gave it the second coat, this was going Ok now, allowed that to flat off. Then the base coat, again dead light dust over, again after 5 or so minutes gave it another .


Now the laquer, coat one, coat two, coat three. It looks Ok, in the odd area looks a bit dry, but with three coats, will that compound back with 1500 & G3.

Woody you are a real brick!!

PS, will it darken a shade when it cures off????

[Woody]

Glad to have been of assistance
the colour will tone down a bit when you polish it
We use 2000 wet and dry paper wet before the G3 but go carefully ! it is easy to go through (especialy on the edges)

Ya @lex,


Sure will, I am virtually finished, allow me 24 hours to fit the car up, and I will post those images.

Woody's advice was invaluable, its a crying shame he does not offer live chat!!!!

The moral I think is patience, follow instructions, and the great finish will be the end result, I am no longer a 2K virgin ....... What a relief, no blood or pain either!!!

24 hours.... can't wait.

i suppose woody is a busy man, painting mini's all day long to be able to offer live chat.

yeh i think your right about the moral being patiance, following instructions. but you are selling ya self short a bit there webweaver. the ability to follow and relate the instructions, dedication, determination having the bottle to start something new and a fair bit of skill.
well done mate. congratulations on popping ya 2k cherry.

cheers

@lex,

My cherry 30 came out of the garage today, to go for its MOT, looking good, but not ready for photos, a few panels need a bit more buffing, so here is another 30 I own that benefitted from 9 litres of Black cellulose.


Woody, it needed that much to get the lustre honest!!!!

[Senile Old Git]

well , this is the end result, all done in my garage at home, the car as you see is red. at times the air was blue.


Again, a million thank you's to Woody who helped me through the process

[@lex]
