+1 for peelaway 9 (marine version).
I've picked it up in Sydney in bulk 20kg tubs @ $220 at amazing paints.
I could have sworn I posted a reply to someone ages ago about doors but cant find it now
Needs no neutraliser/rinse unlike their other ones, needs coating paper but this is a plus as it stops drying, and is good for safe lead paint removal.
I've used this on house (lime render, architraves etc) and furniture with little complaint. Could leave it on cedar, pine etc wrapped up for 2 weeks and would pull paint of intricate wooden/plaster moulding perfectly.
The only times I've seen it fail is when it wasn't used correctly, mostly from people who read the instructions then decide their own ones (ie cheap thin smear thinking it'll go further etc).
Any time things aren't going 100% your way with the stuff, you've gotta take perspective and think 'how much would I be swearing/cursing, how long would it take and how much would it cost if I was doing it with abc method'. 9/10 times with the work I do I'm happy with the chosen medium.
Jon, your ######## detector is working, but the needle is fluctuating

. The same as with all of these strippers, depends on what you're taking off, what it's sitting on and how it was prepped/applied. I HAVE stripped doors with that stuff ages ago that almost worked like the ad, and have stripped other stuff that had me cursing- although if it was my business I could understand why I would choose to promote the former

.
Having said that it's hard to believe looking at the ad they're not selling magic paint stripping wands
Peter- with these types if you want to take the stain off as much as possible you have to catch the magic time when it's saturated the solid coating as much as it will and is still liquidy/moist underneath. Going either way is very counterproductive in the long run (would explain why they print test patch notes on their cover paper).
In your case I'd suggest buying the smallest sample sizes if possible to try different brands to see what's going to work best (I've only bought a few 20kg tubs myself) with the varnish before commiting to the bulk size needed for a boat.
Cheers,
