Tamiya white putty and primer

[porschercr]

I've got to fill a few small areas on the sail panel of a '69 Boss 302.

I've used Tamiya white filler, will I need to use a sealer, so it won't show through final prime and paint?

Thanks,

Trevor

You shouldn't have a problem once you prime over top of the putty. Never had a problem with either white or grey Tamiya putty bleeding through.

My experience with the putty was not a good one. I was trying to level a large area, and it kept sinking to the point it kept bowing the styrene underneath.

Carefully check after primer to make sure it doesn't sink. ( Mine actually sunk before any primer). Maybe it's me, see what others think.

Good luck!

Tamiya White putty doesn't work well for filling at all. It seems better suited for filling in scratches after primer. The Tamiya Gray putty works much better for filling.

I'm surprised to hear about the problems that others have had with the Tamiya Putty. I normally use it for small corrections and body blending parts. A few years ago I built an '80's El Camino with the SS nose. I completely filled the license plate recess in the tail gate and you still would never know any work had been done on the tail gate at all. My only suggestion would be to primer the area to make sure it is smooth. This can sometimes require some additional filler, but the primer will show you any imperfections just like the rest of the body. When it's to your satisfaction just go to the final color coat.

Thanks for the input David.

Primed the body on the '69 Boss 302, with Dupli-Color, still have putty showing through. Suggestions?

The picture looks as if the area was rough sanded but not sanded smooth with a high # sand paper. I would use an old #11 blade and put a smooth layer of putty, just enough to fill the scratches. After it has dried go over the area with a sanding pad in the 1500 to 1800 range. I would try sanding at two different directions to help eliminate scratches and use very light pressure letting the sanding pads do the work. Another light coat of primer should tell you if you're getting to the finish you want.

Not sure how the Tamiya handles it, but with regular putty, I will put a light coat of THIN CA glue to seal the area. Then sand with fine sandpaper.

These Lacquer based puttys are my least favorite. 

It does  look like from those pic's that you need one more application 

and follow through with finer grit sandpaper.

you are nearly there,

A lick of thin CA glue is good recommendation.

The peimer was a bit "dry"  when I did it.

Thanks for the suggestions...

Regular car body filler works for me. You can also use a finishing product called "stopper" for fine pin holes.

Trying to fill large areas with putty is most likley not going to give you results you want. On the Mustang above, I would suggest cutting out a thin piece of styrene to fill that area, glue it in with super glue and sand down to level it out, you might need to glue and sand down a couple of times.Then a bit of putty to fill in any remaining bits that the piece of styrene didn't fill in and you're good to go. Putty shrinks, especially over time. What might look good initially, will eventually cave in after some time. Putty is good for small fixes but I don't like using it to fill in. Covering up door/trunk/boot/bonnet/hood scribe lines, slice a thin piece of styrene, glue it into the seam and sand form there, a skosh of putty to take care of nooks and crannies.... My $.02, ya get what ya pay for.... -RRR

Thanks RRR, Appreciate the advice.
