I couldn't find this Ave stuff anywhere online that ship to my country. My obvious option would be eBay but I didn't find it there also. I got some tips and good advice about a "Perfect Plastic Putty" in a couple other forums so I decided to give it a try and ordered a squirt bottle. Let's see when it comes.

Thanks,

A technique for larger areas is cardboard and CA. Make your part from coarse cardboard like shirt backings or internal packing and soak it in CA. You get a fibrous plastic. This was used in the auto industry for rapid prototyping before 3D printing. This Guy


Cool! I love these old school techniques!

NCC, I concur with El Gato. Nothing beats AVES Apoxy Sculpt for a good strong seam joint if you can get it. Won't shrink. Workable for up to a half hour. Dries hard yet is still sandable and carveable. Can be smoothed with a moistened q-tip or use your finger to drag out and feather the edge thus eliminating a lot of unnecessary sanding.

Perfect Plastic Putty doesn't copme ina squirt bottle, at least not the ones I'm familiar with.

PPP, as it is often referred to by modeling experts :lol:, is a water based paste that goes on creamy and can be smoothed into your seam joint with water and a q-tip or a sponge applicator (or your finger). Dries very hard in 10-15 minutes so start sanding after about 5. Great as a filler putty where no flexing of the parts will occur. Has no strength as it is NOT an epoxy putty, strictly for filling in surface imperfections and seams.

I used it quite liberally to fill the grid lines on my 1/350 TOS Enterprise and it was a slog to sand it off after a few hours drying time. I ended up using 150 grit sandpaper to knock it down to the level of the plastic before moving on to progressively finer grades of sanding films.

It looks a squirt bottle for me. Wrong word perhaps?

I'm going to have to look into this as well. Bondo is my material of choice for surface scratches and minor seam and surface repairs. The problem I've found with it at times is that it cracks.

I'm going to have to try this. And I hope you don't mind if I steal your deflector idea on a future build.


I would be honored. I mounted the smaller defector dish flush with the rings, spike removed. I left the outer most ring and filled the rest up to the dish.

Totally hate the tamya putty... Like you I always get pitting in it...

I mainly use the Humbrol, the vallejo or Mr Dissolved putty depending on the situation.

For bigger gaps, I use Ave Apoxie sculpt, but that stuff dries really hard to it's impossible to sand, so you need to "sculpt" it before it cures...
