You still need air fed as its a 2K product, Primer plus Hardener.
There are single Epoxys around but they couldn't hold a candle to the 2K stuff.

Fergus, keep us all updated on how rollering epoxy works as I'm also doing a beetle and though I have access to a booth at work we can't store it while I work on it.The plan is to do the prep and inside at home then take it to work for the outside top coats.
Let us know how easy it is to sand and are you doing the awkward detailed places with a brush?

I've just received some Jotamastic 87 from an ebay seller for £43.90 and free delivery
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=180682217621
After seeing langy's comment about someones product being out of date I was worried that could of been the reason why mine was so cheap, but the mfg date on the tin was June 2011.
Quick question - I'll be using fairly small batches (about 250ml at a time) so am I OK to use weight to get the correct ratio of paint and hardener? We've got some digital kitchen scales, which measure in 1g increments, so I could borrow those while the wife is out

^ bargain.
Jotamastic doesn't seem to have isocyanate hardener, unlike normal automotive epoxies (except a pricey House of Kolor one).
I'm not using mine topside, except the inside of the boot, it's so very hard, and hard to sand, and automotive epoxy lays and smooths/flows better (but has the isocyanate issue). Underneath I've done a mixture of brush, spray and roller.
Well I don't know what I was reading before. Found two products with datasheets that were very much the same in essence, one looking a slightly reworded version of the other. The epoxymastic 121 and 87 are so different in so many details. Very puzzled now. Sorry.

Using the foam rollers that you see recommended for the Rustoleum repaints leaves a slightly textured finish, I'll probably spray a guide coat tomorrow and find out just how hard it is.

I was going to buy some from them[metalflake], they are close to me. However I only wanted a litre or so, so I bought from paints4u. I mixed the first coats by weight, mixed something like 200g of epoxy. I used some cheapo salter digital g scales and it was fine.
I have something to do tomorrow and I think i will mix something like 25g of epoxy!

The Lechler epoxy.
Ok, it's hard! Rubbing down with 320 is slow work. I think I'll add some more thinners next time and see if it goes on any flatter.

Would it need completey flatting down or could it just be keyed then gone over with highbuild then flatting smooth?

youd really need it close to flat before the high build , could use 240 dry to speed things along a little?
That's where I'm going with it, it'll be a week before I can get back to it now.

got an answer on the jotamastic 80 vs 87..
Jotamastic 80 and 87 are essentially the same product, but Jotamastic 80 has lower volume solids (80%) than the Jotamastic 87 which is 87% volome solids.
