There are various Rub N Buff threads, but I have not found a definitive source for the best overall techniques. Can the Rub N Buff Masters please step up and explain the following:
1) On Sintra/ABS, should Rub N Buff be used directly on the material, over primer, or over another type of paint?
I sanded my armor with 220 grit (sintra) then used krylon sandable primer, wet sanded with 330 grit, spray painted with Krylon dull aluminum, then applied rub-n-buff.
2) How finely should the surface be sanded?
See above answer.
3) Clearcoat?
I used Krylon Matte Finish on my jet pack over the rub n buff with no problem. I've recently experimented with my armor because right now the color is so awesome and it really looks like metal. When compared to the silver on my jet pack, it looks so much better (the jet pack was rub-n-buffed under the finish). SO I took a scrap piece of sintra, painted, rnb, then tried the matte finish and also tried the Krylon clear glaze. The clear glaze did not work well, kinda looked like oil and water. The matte covers fine but I think it detracts from the finish a lot. It goes on fairly smooth so long as you have buffed well but can be just a tad grainy. You can r-n-b over the finish and it is pretty nice but may be a bit grainy in some areas depending on the matte coat.
4) Rub n Buff with cloth or hand?
For my armor, I used my hand to apply then buffed with kleenex
5) When applying, can you estimate the diameter that each application spreads out to (in other words, how much are you using)?
Well, I use about 1/16-1/8 inch ribbons from the tube at a time and start is a spot and spread it out from there. Then just go to the next spot. I found doing 2 coats (buffing between each coat) gives a more even finish- you will see spots that need more coverage so just add it.
6) (Optional extra credit) If I Rub N Buff my dog, would it pass as a digital pet?
Only if you shave it first!
Thanks.
