Polycarb paint on hard bodies

[Corpse Thrower]

Deciding on a paint job for the Blackfoot Xtreme...

 

Love the purple/green flip, but its polycarb paint...If I put a layer of black acrylic on first, then the polycarb flip paint, then a layer of acrylic clear, will it stick together, or react?

Anyone here mixed the polycarb paints and the standard hardshell paints? What results have you got?

I've just painted a scrap section of the Lancia 037 cockpit, so I guess we'll see.....err....thats the same plastic as the hardshells, isn't it?[:$]

[DJTheo]

As far as I have heard they don't react when completely dried and you give several thin coats. You could even use a lexan black ground as the PS colours adhere very well on hard plastic, I did the same to use the anodized lexan silver on my Frog wheels  

The cockpit is from different material afaik, better try on a driver tree.

Well, it hasn't reacted yet.

I sprayed the Metallic black, waited about 15 minutes, sprayed the Purple/green polycarb paint, waited 15 minutes, then sprayed the hardshell clear. Looks nice, but needs some more clear and then a good polish I think.

If the polycarb paint sticks to hardshell  plastic ok then I suppose I don't really need the black base coat, as the blackfoots body is already black. I can go with the flip paint topped with clear only.

Do I dare to try it?[8-)]

Never an expert on painting, but if you've got plenty of black to

basecoat, why not use it..?  an extra layer won't hurt the detail,

and will give that extra bit of strength to the paint []

Dare it, as I had my info confirmed but wait for the lexan paint to dry completely few days before you spray the TS-13 clear coats.

Righto then, I'll do it!! Wish me luck!![*-)]

BTW, Lexan paints contain Etch chemicals which will eat into your Styrene body, have a nice day, and GOOD LUCK!

[DJTheo]

Not all, I think more Pactra paints etch into the lexan, thats why you cant strip them, but Tamiya and Faskolor are strippable.

I managed to strip Pacta paint off a polycarb shell the other day.. It was hard work, but came off with Nail Varnish Remover.

It was brushed on Pactra though... [:|]

[Corpse Thrower]

Its done. Came out well. Now for the clear!!

[Corpse Thrower]

Well, I think I stuffed it.

The paint is peeling off the body like a skin. I had a run on the side, so I sanded it back, reapplied the paint, but it still showed the run, being a clear coating with matallic flakes I should have realized this would happen....anyway went to sand it back again, and the paint just started peeling...so much for the etch theory. Now I have to strip the whole body and start again. Question is, what do I use to strip polycarb paint of the Blackfoot body? Is it the same plastic as the white bodied cars? It feels much more pliable, so I'm guessing ABS plastic?

Stupid me for washing the body with hot water....not only did it peel the paint off, the rest of it has gone chalky....acetone restored the finish, but I think it will go chalky again.

 

But, the tailgate came out brilliantly with a couple of coats of clear and a light polish....wonder if I should try again?

Yes and this time listen to what I wrote above, let the lexan paint dry for a couple of days, hurry is the worst enemy of a paintjob.

I would strip it with easy off oven cleaner. 

What did you use for a primer?

[MikeT]

Corpse Thrower- All of the Tamiya Hard Bodies are STYRENE ( NOT ABS ), Styrene is Styrol Resin, as a polymer of Styrene ( POLYstyrene ).

The Only ( AFAIK ) exception to this rule is the Holiday Buggy Shell, which is made from Poly Ethylene. Which is NOT To be painted.

I agree with Shodog, what primer did you use?

Hey Corpse thrower, Go for it you know you want to.......

I agree with the other lads, make sure you use a good undercoat, and more importantly be patient. Wait for it to dry before you start to lay coat after coat on, it has to cure.

You will have to let us know how it went, I have a hard body that I want to paint and would love to know how the flip flop paint  went on, have used it on my lexan shell and loved it and think it would suit the model that I am building at the moment.

Good luck with the painting.

Okay, I will not only try again, but as you say take it easy and don't rush. This happened only because I was trying to get the body in clear last night, but then noticed the run.

Another thing that might have helped is to rinse the body in COLD water rather than hot. I reckon if I used cold water this wouldn't have happened. Take note, punters!!

Shodog and Mike T......no primer used[:$]

I was going to paint it black before the polycarb paint, but the shell is already black, so I thought whats the point? Perhaps the acrylic black would have gripped the plastic better than the polycarb paint...dunno really.

I'll try the oven cleaner tonight and post pics when its stripped.....hopefully it comes off easy being 2 day old paint.

There ya go. Acrylic black isn't whats needed as a first coat, to get

the paint to stick properly use a proper primer such as Tamiyas fine

fine primer. Once you have painted the black put the shell to one side

for a few days to make sure it is fully cured before using the flip

paint. Again leave it for a few days more before clear coating. If you

then want to deal with any small defects or to polish it make sure you

leave the shell for at least a week so the paint fully cures and

hardens before attempting to work on it.

[Shodog]

Terry is correct, you have to have a good primer coat so the paint will stick.  Take a look at this Monster beetle body I am doing.  You'll notice that I flatted the paint with 100 grit paper before each primer coat.  this ensures a nice smooth finish

[Corpse Thrower]

Yesterday I coated the body in oven cleaner, the same stuff I stripped my other hard bodies with.

Spent half an hour with a stiff brush, and expected no paint to be left, just like my other bodies.

It didn't even touch it!! Not even a little bit!!

Anyway, I cracked it and attacked the body with 250 grit sandpaper....that got the paint off...hehe....don't mess with Uncle Corpsey, especially if he has a sheet of coarse sandpaper!!

I have no idea how I'm going to strip the tray though.....

Lucky I bought some primer....looks like I'm going to be doing some serious body prep to get rid of the mile-deep scratches!!

What other products could I use to strip Lexan paint from a plastic shell? Nitro fuel? Then again, isn't the Tamiya paint impervious to that stuff?

I'm this close to chucking the shell in the bin.....

Hi,

Tamiya PS paint won't dry out to be hard, they are flexible as they are suppose to be used for polycarbonate bodies. They will dry like a skin. If you do polishing, I am afraid...

PS paint has thicker particles than static model TS paint. I have only used PS5 (black) for rear wings or side mirrors, ending to have a semi gloss plastic look.

If you really like that purple/green paint, you can try DUPONT, if I got it right, they have this type of paint available in spray cans, besides, they also have mirror chrome paint. A black primer must also be used in order to get that changing color scheme. (I am not sure if they work on plastic!)

Did the spare wheel of my Pajero with PS black as my TS one had finished and did a very nice finish and adhesion, despite not using primer
