Paint Finish
« on: October 18, 2006, 10:20:03 am »

As I am new to modelling i would like some advice on painting an ABS model.
I am in the process of constructing a Robbe Najade model and enquireas to whether or not this ABS hull requires and undercoat before the final coat of paint. Any help from fellow modellers would be appreciated

You will need a primer.
I assume you will be using acrylic paints. There is another thread on here about paints and Halfords cans seem to be a favourite choice.

You should also key the hull the sandpaper to help the paint stick.
320 grad sandpaper should do it.

But I am sure you will get a wealth of advice on here, try trawling throught some of the other threads as well.

Good luck :)

Right it is quite simple really,go down to your friendly local motor factors that sell AUTOMOTIVE paint to the body shops,such as Brown Brothers or Partco and ask for a plastic adhesion promoter 3M do an excellent on as does Body line,these products are available in aerosol form and are used by body shops prior to spraying bumpers and plastic panels.All you do with the stuff is simple spray on 1 coat,leave to dry,DO NOT RUB DOWN,then spray on as many coats of primer as necessary,rub down primer with 180grit wet dry following up with 400 then 600 and spray as many top coats as necessary.whilst you are at the motor factors buy some panel wipe,this is used to degrease the model,wipe on wipe off simple as that,ah ha I hear you say a gallon!!!! yes it will last for years and is handy for all forms of degreasing,also buy some TAC rags for getting rid of the dust on the model(used by professional paint sprayers prior to any application of any paint ;)).

It is well wotrh getting all this stuff before starting to rub down your model,as it is well advised to degrease with panel wipe prior to rubbing down as the last thing you need is to rub in any grease into the plastic,rub the hull down with 600 no coarser prior to the application of the adhesion promoter etc,if you need any more info just either post it or PM me.I do know what I am talking about due to the fact that I am a professional paint sprayer.

Stavros, just out of interest:
A standard primer doesn`t make any sense? It has to be a plastic adhesion promoter?

White Ensign read the post it is as I have said Adhesion promoter first,primer second,it does not have to be plastic primer,as you have allready applied a promoter,Any primer will do.If you all use this system you will be amazed by the finish you will get.The promoter will allow the primer to lie smoother on the surface believe you me,if you do not believe me I think it was shipmate 60 who took my advise,someone out there did and was very impressed.Believe you me IT WORKS,hundreds of body shops cant be wrong or can they

Hi Stavros- sorry, looks like we have crossed our wires- now I`m with you.

O.k- will go for that as my son wants to spray his boat next week. Though I am glad for any advice in that way as I never use to work with plastics...  :P

Thankyou.

depends what colour you need but if its a bright gloss try international japlac its for plastic as well as wood and metal and ive found it doesnt need any primer .it covers great and adheres well to plastic but it only comes in gloss so its ok for speed boats yaghts etc.its also easy to apply with a brush and leaves no brush marks ,does what it says on the tin!!.

Stavros,

Correct me if i'm wrong but the plastic promoter, does it not also bind the paint to the plastic so it will not crack or peel off...

Good stuff then Stavros. :)  I'm restoring a plastic Robbe "Wotan" hull at the moment. Would a coat of this also benefit a previously painted hull that appears to have NOT been primed (black gloss coat coming off in a couple of places). I think I will take it back to a bare finish and start again at around 400 or 600 grit? :-\
Thanks for your help

MTB yes do it take all the paint off with 180 grit,yes I know it leaves scratches 3m adhesion promoter,primer 2to 3 coats to cover finish off with 600 wet dry,if rubbing down wet leave to dry off for at least 24hrs in warm place then paint with your final colour.You can also rub primer down dry but for goodness sake wear a mask and change your paper often

Stavros,

You ought to write a piece for one of the modelling magazines. The practical advice you have on painting matters would be immensely useful to a lot of people.

Why not go for both (or are there copyright probs once offered to a mag) that way you should reach the widest possible audience and educate even more modellers :)

Happy scribbling

Go for the mag Stavros. If it is published most people will read it anyway and you will get a few pennies in compensation.

Stavros,

You being the author should have the authority to place it in any position as long as you let people know it appears in other publications...
Thats what happens over here anyway...

I think you will find that magazines will require articles to be offered to them on an exclusive basis. However, once publication has taken place you are free to offer it elsewhere.
