I have a 17' aluminum boat I am turning into a duck boat. I want to paint it camo but it has a vinyl sticker sticker and stripes bow to stern that need to come off. I have tried a heat gun and scraper which works but it's very slow going. Does anyone have any suggestions for a stripper to dissolve them?

I have used a heatgun and slowly peeled for hours and it was a PITA. Just googling maybe you need a Whizzy Wheel.

Can't remember the name of the stuff but most auto parts stores sell a product to remove decals and bumper stickers. Not terribly expensive. Might work.

Just my personal experience but I think it's just a slow process. I used a little heat and a plastic scraper on my glass boat.  Too much heat and it made it worse. Too little and it just wouldn't come off. I scraped the stickers and then used goo gone it think to remove residue.  It was brutal but in the end it turned out well.

It probably depends a lot on the adhesive used and how well the surface was prepped. Chemicals may work like a charm. Just have to have the right chemical for the particular adhesive.  

In my experience any removal, be it commercial flooring or decals, is a combination of mechanical removal (scraper, grinder, etc) and the proper solvent.  It's never easy if the job was done right ahead of you. 

PB Blaster makes a spray designed to take decals off.   I've use it and it works ok.   Heat gun helps also.  (All my experience is with a tin boat)   Once you get a corner of the decal lifted off,  I found that locking on with a pair of pliers and consistent pressure worked best.

The spray can had a little red tube you could install in the spray valve and be very accurate where you sprayed the solvent.   Sometimes I could pull the whole decal off in one piece.    Decals that had been on for a long time and been pounded and scraped against trees often are harder.  Sounds like an afternoon 3 or 4 beer chore to me.  Gear up prior to starting.   You'll need a razor scraper and extra blades, solvent and pliers that can grab and pull on a decal without tearing it, and a blow dryer/heat gun.

(That solvent smells nasty and most likely isn't good for you so work in a well ventilated area or aim your shop fan to blow the fumes away from you)

 

Thanks for the replies. Sounds like the slow scrap and peel is going to be the way. Maybe the neighbor's kid would like to make a few bucks lol.

Spray "Goo Gone" on the decals and let it set for an hour. It won't dry. Then scrape the decal off.
