XTC 3D Print Coating Epoxy Kit

Chanced upon this on an online forum and decided to give it a whirl. Used it twice so far and very impressed, easy to dispense, mix and apply and gives great results on 3D prints. Minimises sanding and easy to paint, already ordering more!

I bought this to try making board game bits trays smoother and kinder to cardboard/plastic that was getting caught on striations and layer lines. A single coat of this already made such a fantastic difference, but once I did the second the smoothness was like no other.
Highly recommend. Have used about 30ml (final combination vol) to do 2 layers on 5 decent sized trays so even this small bottle is going to last me a while.
Only feedback would be to get more than one sponge brush as it's unlikely anyone would use this whole bottle in one 15minute session.

I was really surprised how well XTC-3D worked on my 3D Printed parts. The ability to reduce my post-processing time of parts was amazing. All parts came out really shiny and super smooth. The XTC-3D ability to fill in gaps, pin holes and seams was amazing. Sanding was a breeze after this. The absolute minimum amount was used as the saying goes, "a little goes a long way". The amazing properties of XTC-3D are a must for COS-PLAYERS and others in the 3D print community. Well done SMOOTH-ON, a fantastic product!

Some good youtube videos on using this.
Got to put it on a little thick. If its too thin you get a shiny surface but can still see lines. It appears as though the XTC has a strong surface tension which means it fills in the cracks and you get a contnuous smooth surface when dry. Dries in about an hour.

Sands well.
I think maybe best approach is to put it on first and then sand and fill, if you need to. Then add another thin topcoat for glossy surface (if that's what you want).

Because you have to put it on a little thick it doesn't cover as well as they might lead you to believe but coverage is very high compared to (say) paint. A little goes along way.

I used an eyedropper (well two actually) for small parts. You only need 3mls spread onto aluminium sheet "tray" (see videos) to cover the object. Keeping it thin gives you a longer working time. Keep going over it to stop drips and buildup in detail crevices.

I think its worth the money for small or detailed parts where filling and sanding is especially difficult or time consuming. Easy to use, gets rid of the ridges, goes along way. Also gives a nice gloss finish, if that's what you want and it dries fast (1 hour).
Not use it for giant flat sided pieces.

I also rescued my brushes just fine by rinsing them in Acetone after use then washing in soapy water. I used very small painting brushes as my models have finer details.
The mixing cup etc is a throwaway. Gloves are handy. MSDS indicates this stuff not "good" for you.

I bought a kit to clean up up a 3d printed model i had made, after only one coat the finish is almost perfect ( some run lines ) once cured it sands smooth with some wet 600 grit sand paper.

Definitely wear gloves!!
