Reply to: Failed soft spot repair

Message body

[quote=waiex191][quote=raisehull]Several questions for you, as I am preparing a similar repair. 1) How big an area are you trying to repair? 2) What was the spacing of your injection holes. 3) Did you inject one hole until it oozed out the neighboring holes,then tape those holes off? 4) What epoxy were you using? 5) just how soft was the area? 6) what do you think lead to the poor results? Thanks in advance.[/quote]

1) I'll post some pictures and you can see.
2) About 4".

3) I was not getting oozing in the neighboring holes, so I just injected as best I could in all of them
4) System 3 like this: [url]https://www.amazon.com/gp/product/B00UVH2PB4/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1[/url]
5) It seemed pretty soft.  Not sure how to put a measure on it.
6) The foam was wet!

I decided to cut out a panel on the top.  I practiced on a scrap from the old boat.  That is a circle/straight line cutter tool for the dremel.  Shown is circle mode.  It uses a little router/cutter bit.

Here is the straight cut after I did the two half circle cuts on my hull.

Top popped off.  The foam was wet!

We heated up the inside of the boat.  Our hangar thermometer was removed from the wall and put in the hull.  It read 120F after 10 minutes or so.
