Anyone used "3M 4200 Marine Adhesive" before? I am going to remove my intake grate and re-install, West Marin said this stuff works well and should seal up the grate with no leakage. Just wanted to find out if anyone has used it before and what were the results. Everything else I have used by 3M has been great.

i've used 5200 before and that stuff is off the hook for sealing below and above the water line. not sure about 4200 though.

I used 3M 5200 when I put in my ballast thru hull below the water line on our last boat.

5200 in not considered to be removable, 4200 is a slightly softer version for use in applications that are not permanent. Both can be used under the waterline.

Used 4200 to attache my depth finder to the inside bottom of my hull and this stuff is the shizz! Make sure to clean & degrease the area it will adhere to. Acetone ought to do the trick.

3M marine adhesive is the best out there, that simple. I have used the 4200 to seal the new brackets for my swim deck. Easy to work with and does the job perfectly.

How are you guys dispensing the 5200? I bought some from Home Depot and it didn't work well in a cocking gun...

Caulking gun, the other one sounds like something else... <BR> <BR>sorry, I am not the grammer police but I though that one was funny.

Considering Wakemakers.com said I could use the 3200 series, I am assuming the 4200 series should only be better? They did have the 5200, but I thought "permanent" was a little to aggressive if I ever wanted to remove the intake grate again.

Use brake cleaner on a paper towel and you can clean that stuff off nicely while it's wet.

The 4200 is fast cure, When you do not want to wait the 7 day full cure time of the 5200....

Perfect, thanks to all who replied, appreciate all the feedback. Went ahead and used it today, should dry quickly in the 100+ degree heat!

5200 come's in fast cure also!

so the 4200 isn't permanent. Is there any trick to removing it when it comes time?
