Just starting out - Order for Prime - paint - finish
Posted by Orsm on Thursday, April 16, 2020 2:44 AM

Morning everyone

New here, first post so be easy on me.

I am in lockdown so have bought all the gear and and have no idea ...... well sort of.

I have made 1 car so far and it was not bad but want to get better, with your help I would like to understand a bit more. I have watched countless youtube videos, and read forum messages on how to prime, paint and finish your model. The following is what I think is right but is most likely wrong, the products I have chosen are mainly from what I have seen or read good reports on. Please can you help and tell me if I need to alter the method I am thinking of doing on my current car.

1. Prime

I rub the body surface down with either a 400 or 600 grit wet n dry in soapy dish water, making sure the surface is scratched so the primer bonds to the plastic. After this I clean the car with soapy water and run it under water, I then leave to dry.

The Primer I am using is Halfords (UK Store) grey plastic primer rattle can, I have used Tamiya fine surface primer and it had a lovely coat, however it can be quite costly. Halfords Grey plastic primer is bigger and cheaper, I have seen lots of reviews on here I think saying it is fine. It sprays fine but leaves a slight rough texture, I do 2 coats, 1st coat i leave for a few hours and apply the second coat a few hours later. It dries quick. Then leave 2nd coat to dry over night. I then use a fine grit wet n dry to leave the surface smooth.

 

2. Paint job

For the main body I use a Tamiya rattle can. A few light coats followed by 2/3 good coats. I do not sand inbetween. I warm the can up in hot water to increase the pressure and don't spray to close.

 

3. Clear coat

This is where I start to really need help, I am at this stage now and wont proceed till I am sure I know I have the right info. The car body is now painted and looks good. From what I have seen I am now supposed to lightly wet n dry the paint work. I have ordered fine grit sand paper, the finest I have is 1500 - Think I have stuff arriving that goes to 8000 grit. Am I supposed to wet and dry the paint work lightly? if so with what Grit.

I have Tamiya clear coat TS 13 - How many coats ? Do I do any sanding after the clear coat?

 

3. Polishing

I have novus plastic polish, 3 bottles, Number 3 - heavy scratch remover,  number 2 -   fine scratch remover and number 1 - plastic clean and shine. Seen good reviews on this so hopefully get a good result. 

The last question is if I have decals at what stage do I place them on the car ?

I know there is never a right or a wrong way, I just need the basics to get a good shine.

Thanks

Not familiar with that primer- I am in US, but order of work is correct.  If there are decals, I put them on before clear coat.  Decals go down fine on glossy paint, no need to glosscoat over gloss paint.

Whether I gloss coat depends on the era of the car.  In the old days neither racing cars nor factory stock had clearcoats.  Polishing the final color coat makes a realistic shine finish.

I only clearcoat customs, rods, and modern cars.

On how many color coats, it depends.  Hard to get a level smooth dustless finish, so I keep put on coats till I get what I want.  I start out putting down several thin coats to build up enough thickness that I will not polish through it.  Then, one last heavy, wet coat.

I usually use gloss enamel, but I have used those Tamiya rattle cans.  They do produce a great gloss finish with little work.  Usually two light coats and one heavy does it.

Just make sure the cap on the spray can is aimed at your work!

That sounds a lot like an "ask me how I know this" kind of statement! Big Smile
