Rustins plastic coating - how to size?
Hi folks,
After a demoralising run with CA I am trying out Rustins. Did a batch of sierras using Les's dipping method to apply, and it looks good, but man it goes on thick and now I have fit issues! Going to try with some thinners added next time.
Anyone out there still using it and have any tips in terms of number of coats, final polishing technique of choice etc.? A search of the forum suggests it was popular a few years ago but hasn't been talked about much lately.
Cheers,
Danny

Yes it is thick, but like CA, you need to allow for the resultant final surface thickness by under turning your blank. Once you go to CA or any other thick surface finish you need to go to cone bushes for finishing (cutting board/Delron etc). If you stick to your metal bushes you will always end up with oversized blanks, and more often than not, a dip in the blank surface at either end from sanding.
I went away from using Rustins on pens due to issues I had with with the end drip/end sealing but use it on knives and kitchen utensils. I use buffing for final finishing for the Rustins, but wait a good while to ensure it has fully cured and hard.Neil____________________________________________Every day presents an opportunity to learn something new

Yeah, I undersized these similar to what I would for CA but it ended up quite a bit thicker... Not sure I could undersize enough without cutting all the way back to the tube! Will try one less coat and a bit of thinning.

it should be a fairly thin mix.
Mix it 4-1 and see how it flows of the brush, if you find it too thick add some of their thinners but only a very small bit at a time.
It is wet on wet so an hour between coats, only mix in small quantities.
Pens generally 3-4 coats and use a very soft brush like the girls use for folk are..
They say leave 24 hrs but I would always advise 48 hours before burnishing if needed.
When applying the finish do it in the kitchen after tea as it is generally cooler and dust freeJim Carroll

Thanks Jim! I am wondering if dipping has increased the thickness significantly over brushing it on, but I generally cause a disaster when I pick up a brush, so dipping is appealing. I do like the results so far, just need to deal with the sizing problem.

Dipping is not a problem as long as then ends are sealed so no finish goes inside the tubes.
The plastic coating is a fairly good self leveler so using a soft brush with only a minimal amount on the brush should give you good results.Jim Carroll

My incompetence with a brush knows no limits Jim! I reckon I can find a way to stuff it up, probably with a particularly nice blank, too...

I only have very limited experience with it George, but I get a satin-ish finish (verging on gloss) using the technique from the instructions (a quick blat with fine wet and dry and then the Rustin's burnishing cream) and a higher shine if I treat it like I would CA - sand up through the grits with micro mesh (wet and dry first if I need to deal with any problem areas), then a plastic polish.
