Hello,
I am starting to put together my ARF PT-19 from hangar,
it lists using rubbing alcohol to remove felt pen marks also excess epoxy, I am having trouble buying this product.
Any thing else I can use?

Any kind of alcohol available (hardware store, drugstore, etc.) will work just fine for removing magic marker.

Perhaps it's a language difference? In the US "rubbing alcohol" refers to isopropyl alcohol, and it is readily available.
So if you can get isopropyl alcohol by any other name, or (like Bill said) just about any other alcohol, you should be all set.
Try single-malt scotch. It's more expensive, but it'll make your plane smell fine.

I think it is the language difference, I went to our hardware store, your drug store,
I was told No, go to the chemist, fine, but then im told $30 for 500ml also they wanted to no what I was using it for.
Any Australian readers got some ideas?
Thanks guys.

I found this with Google. It is supposed to be readily available down under.

I can go to any Home Depot or Lowes or ... in the United States and find alcohol by the gallon in the paint department. Is Australia THAT different?

Thank you guys for all the info,
Problem solved.

$30 for 500ml?!? That's definitely priced for drinking, although it's no single-malt.
Just out of curiosity, what's the Oz-specific solution to this problem?
-
Car window cleaning fluids might work very well. The arctic grade ones are mainly ethanol.
-
As it is a ARF and the marks are probably on the film covering, then just about any solvent would work. Benzine, Denatured Alcohol, Laquer Thinner just to name a few. Turpentine would probably not work. MEK ans acetone work just fine as well. In a pinch you can even use nail polish remover.

Isocol is available in Oz. Not 100% iso-propyl-alcohol but it's available in supermarkets.
A problem we have is getting what we call commercial purity iso-propyl-alcohol. The stuff from the chemist/pharmacy/drug store is medicinal/reagent purity, hence the price.
-
Grocery store version will work just fine. If I recall, it is 90% pure, the rest water.

Grocery store isopropyl is all over the map. Various stores around here sell 70%, 90%, and 99%. I get the 99% for thinning epoxy and whatnot, and keep 70% around for shrinking tissue on rubber-powered planes and for cleaning up felt-tip pen lines.

Hmm , I can get anhydrous IPA from the local electronics store for $4/quart or so. It's used for cleaning circuit boards.

Methylated Spirits is probably the easiest thing to get in Australia (ethanol+methanol+water+denaturant) that will clean off the ink. IPA is hard to get in NZ too, because it's used for processing illicit narcotics, so the authorities like to assume that anyone with a need for it must be a criminal.
-
Wow. We buy Isopropyl Alcohol here at the local store for like $1 for a pint. Watch out with denatured alcohol. It will remove paint if you rub too hard.
-
Aftershave lotion should work.

Isopropyl will remove Brodak & Randolph dope also. :)
