Re: Using ON OFF on Awlgrip

I think I have seen ppl say FSR is ok is used briefly. Isn't that a milder on/off?

Amazon's inflatable cleaner is amazing stuff. IMHO
Sticky PVC tubes have nothing to do with the acid.. PVC is simply a poor choice for longevity in the UV. There are thousands upon thousands of PVC boats that have never been touched with acids that still suffer from stickytubeitus.

Our 1998 Zodiac Cadet Fastroller got sticky in under two years and had never been touched with anything but soap, water and UV.

Yes but I would use the ON/OFF GEL not regular ON/OFF. ON/OFF GEL is milder... I won't use regular ON/OFF even with immediate rinsing..

DON'T

On off is muriatic acid, it is used to condition swimming pool gunite and cement sidewalks.

Also you can wax and buff awlgrip, but once the outside gloss is broken on the paint you are committed to waxing all the time.

Now I read that it damages Awlgrip but how bad is the damage? Can it be any worse than the mechanical damage I would do by rubbing and scrubbing and scraping?
I use ON/OFF Gel on our AwlCraft paint. I find it to be a tad milder than regular ON/OFF but still effective. They key with anything is to be smart about it. Yes, acids can etch Awlgrip & Awlcraft and harm the finish. However if you do small 2' sections at a time and IMMEDIATELY rinse and neutralize that section before moving on you will be okay.

Awlgrip/Akzo specifically says to not use acids but their tech support will admit that if you use it smartly you can be okay.

*Use the acid on a warmer day 80+ is best. This helps the acid work faster and this means less time on the hull.

*NEVER work on the sunny side of the hull only work the acid in the shade.

*Once the tannin staining is gone rinse IMMEDIATELY with a hose then neutralize the acid and move onto the next small section.

*Do not let it drip into the bottom paint

*Be smart about it.....

I have seen Awlgrip ruined by dumb use of acids. It looks very dull and etched. If you work fast and rinse often and neutralize you will be okay... recommended by the manufacturer, NO. can it be done? Yes, if done carefully...
