I tried the citrus strip and the Smart Strip Pro (which they claim would work and did not!)

hard to get to places and close to Gel Coat so stripper would be good. The Dumonds tech support ladies say Smart strip pro would work,
they have no idea what is up, hey just read out of there manual I guess

tough stuff and 10 years old.

2 part varnish is not varnish. It is some sort of epoxy. Probably need to use heat and scrape it off, then sand it.

Two parts are usually Urethanes, like Bristol Finish. If you want a stripper that is sort of friendly, use SOY-GEL soya based stripper. Heat will work too.

I've only had to remove catalyzed finishes a few times. Methylene Chloride based stripper worked sorta on one of the products. Mostly, though, it's been: heat; scraper; abrasives; solvent wash; more abrasives. Hopefully - someone will come along with better advice... 'cause this chit is TEDIOUS!!!

Two part varnish on wooden boats usually removes itself.

Yes... it can. But even in those instances where wood movement followed by moisture intrusion and preceded by bad prep work results in the devil's-brew coming off in sheets... my experience is that there are still lots of areas left where it clings like a bugger.

well as mentioned the adjoining gel coat it the problem so heat is out of question I do believe.
The meth chloride solution is a tough none t mask of,,,the stuff eats up any tape adhesive
Hadn't tried the Soy et...have to read bout some more......pretty doubtful

Perservation tape from 3M. Horrifyingly expensive $65 roll...but it stands up to stripper.

Yes, please. My attempts to use citrus-based on catalyzed clear finishes were a complete bust... and tried a couple.

You may be right about citrus remover on 2 part...never used either...it is supposed to be ok on traditional finishes. Two part should not be used on a plank on frame boat.

The so called citrus product is not citrus based. It has an orange odor that quite frankly gets really really annoying. Check the MSDS. It is less than 5 percent citrus extract and maybe not much is known about the health effects of the active ingredients.

I wish we had a "like" button. Sometimes that's just all I want to say.

Solvent resistant tape from 3M, that's what it's made for. Outrageously expensive, but nowhere near the ballpark of Preservation tape.
