Tex is pretty much the same stuff just lots more expensive. If you have some, have at it. I have lots of the other so thats what I use.
Finshed well with 600 wet and dry(with a hard backer) followed by 800 and maybe 1200 and you may not have to worry about gelcoat
. A quick shot of the correct colour spray paint
will hide it.
Or you could suggest to your wife(if you're quick), as I have to mine on occaision, "If it bothers you so much why don't YOU fix it?"
She has learned not to be so picky about stuff that just doesn't matter all that much, but it has taken me 27yrs to get her(almost) trained.
Why she continues to put up with me is beyond my understanding.........m
