cleaning viser.

[philige]

any ideas getting sanding sealer off the viser of my purelite.the manual says only to use dishwashing liquid, didn't budge. next time i'll take it off before applying.

1)Try a very very small amount of cellulose thinners, (same as you use to make your sanding sealer) appled very very carefully with a cotton bud. Should dissolve it OK.

2) Invest in some overlays. Cheaper and more easily replaceble than a visor.

3) To make your own Sanding sealer get a coffee jar ,or similiar glass container. Pour in about 50 mm depth cellulose thinners,(Rustins have it in their range,or talk to your friendly neighborhood automotive body shop) Then obtain a quantity of polystyrene, the stuff they pack around electrical gear,fruit & vege boxes etc,make sure it is clean. break it into small pieces and put it into the thinners.Keep adding until you have the right consistency.(About the same as paint).You will be astonished at the amount of polystyrene you can get into the jar. Voila! You have done your bit for the environment and at the same time got yourself a quantity of inexpensive sealer.
(It must be stored in an airtight container or the thinners will evaporate leaving you with a solid lump in the bottom of the jar.)
The amount of poly absorbed by a small quantity of thinners will astonish you and any interseted bystanders !
Small children are particularly impressed.

Spray the visor with silicone. Keep it away from timber and your finishing products, etc. in fact do it outside preferably 5 miles from where you work.

Then, when sealer etc. ends up on it, don't worry, it should just wipe off when it is dry. Also stops the inside surface from fogging and stops dust etc from building up on the visor.

Test with the thinner before use. It may sent the visor milky.

Hope this helps.

Neil.
I seem to remember being told by you, or was it ? That silicone spray should not be used within 100 miles (160 kms.) of any wood turning operation as it hangs around and stuffs up any subsequent polishing attempts.
Any comments in light of your above advice?

If it's a Polycarbonate lense you may be in some strife.
Always avoid acetone or ammonia, Upon contact with them, polycarbonate can turn opaque, or cracks may appear on its surface.

John - You're dead right thats why I said:

Keep it away from timber and your finishing products, etc. in fact do it outside preferably 5 miles from where you work.

I probably should have explained more fully and said 10 miles from where you work.

Silicone and woodwork, especially finishing, does not mix.

Apply it well away from the workshop and preferably with the wind blowing away fron the w workshop also. Do it in a park or garden or the middle of the Nullabor Plains or the Simpson Desert or somewhere equally isolated.

John, a word of caution re using coolite as a base for sanding sealer. Have a good friend here that used to use that method. His memory suddenly started to go away and the doctors linked it to this compound. Sadly Joe has not recovered, and can no longer do any woodturning. Maybee someone else might know more about this. ??????

Thanks for your input guy's, looks like I might have to get use to half a dozen spots in front of my eyes. i've heard from a panel beating mate what happened to the car they sprayed 2 pac on ,(in the spray booth) When the glazers put the windows in the factory across the road from them.I use silicone all the time and did not think of what it might do to people around me!Don't think I want to cross the nulaBOUR again for a while, As far as making my own sealer I apreciate the recipe for your brew but as I can claim the small outlay of a tin on tax I think i'll save what brain cells I have for the (necta from the gods).

PCC Sanding Sealer (Polystyrene Coffee Cup) has been around for many years. It is a lot safer to use if made with mineral turpentine instead of thinners. However, I also have heard of memory loss due to the use of this stuff, so in my humble oppinion it really isn't all that safe to use in any form.

If you want a good sanding sealer mix 1 part dewaxed white Shellac with 5-6 parts ethanol. Brush it on and when dry sand lightly to remove raised grain. If you want a sanding sealer that fills the grain use equal parts shellac and ethanol and add a small amount of pure talcum powder. Safe as houses to use and won't send you batty. These are from our new updated version of "A Polishers Handbook" due to be printed next week.

Geez, and I thought it was the grog!!!

Seriously though, I omitted the warning to only use it in a well ventilated area.
