ok i jus bought a 1999 montauk that has a 3inch scuff about a half inch deap you cant see anyfoam but you can see the fiber glass i was told from monahanes and a few other people that marine tex white would be fine for this type of repair becouse it hardens like steal has anyone used marine yes white before any sug thank you peter quincy mass

Peter -

Marine tex is one straight forward material to use. Note - tape off the area. It can be messy stuff.

I repaired my keel rash with it. Make sure it is a warm day with average humidity.

---

Why not patch it with Spectrum Color's factory- matched gelcoat? 1.800.754.5516 I patched my keel rash and a number of screw holes with it. While a 99 boat is "white" and you can save a few bucks using a "white" (note - there's a broad gammut of white) Marine tex - it's just not the same. I found the Spectrum product to be easier to work with, very strong and the repairs are practically invisible. I have no affiliation with Spectrum BTW.

I second the advice using spectrum gel paste kits. We use them at the dealership all the time and they are easy to work with and can make for an almost invisiable repair. If you get it and need some more repair tips, let me know.

---

Is there a limit to how deep you can repair with the Spectrum kit? Just curious as I've been reading that gelcoat sprayed on too thick will crack, not sure if this is different or not?

---

i thought that spectrum was some kinda fiber glass patch is it stronger than marine tex would you use it the same way as marine just mix and put it on

---

with spectrum will i be able to build with i tbecouse damage is on the bottom half of the keal its about 3inches long half to 3quarters deap

Peter -

My keel rash was ~6 inches long and as deep as 1". For the thick areas I did two layers with several days between applications. The area repaired has held up with dozens of launches and retrieves and no sign of a problem.

You may want to read a bit about Marine tex:

http://www.marinetex.com/marinetexepo...putty.html

It comes in two containers and you mix them together. Since I am not great at getting precise measurements, I mix up the entire batch (small size box) and do several repairs at once.

I decided against the gelcoat patch kit from Spectrum for several reasons:

- Spectrum custom colors don't always a match.
- The repair was on the keel and no one would see it so color was not important.
-Spectrum products are not sold in local stores in custom colors so advanced planning is required (not always possible).
-Marine tex does not require gelcoat and can be left as-is.

I have used Spectrum's patch kit on filling holes in the console and RPS and it works too.

My advice is from personal use and following what dozens of members have done.

I've repaired keel rash with Marine Tex then sprayed Spectrum color matched gel coat over the repair. I wouldn't have bothered with the gel coat on the keel but I was doing a few small repairs top side with the gel coat anyway.

I've found the Marine Tex to be incredibly tough and durable. For non-structural repairs and hole filling I use Formula 27.

---

Not seeing this 3", 1/2" to 3/4" deep scuff it sounds like a 3" gash with a nominal width much less than the depth? It's difficult to advise on the Marine Tex without knowing.

The gelcoat repair kits are basically for surface repair/restoration of chips, nicks, gouges and not filling.

Marine Tex and other epoxies with added fillers are quick and simple to use for deeper and narrow non structural repairs but you do end up with a rather solid plug with less flexibility that the surrounding structure.

If the area is wide enough to make the repair using some small pieces of resin soaked fiberglass in several applications you will end up with a close to structural repair that can then be gelcoat finished.
