There's a world of knowledge and experience among you fellas, so tell me the best way to patch drilled holes in the floor and sides of this Montauk I recently bought. They are approx.1/4'' in the floor and sides (35 of them!),don't hurt anything, but looks bad. Thanks,guys

Oh yes, will a good quality spray paint hold up in repairing blemishes on the inside?

Paint is not a great idea being it will not hold up to water and spray paint basically does not hold up well in general. I would wetsand and compound and see how it comes out. Gelcoat is thick and pouros so a wetsanding with 600grit and rubbing compound after is like a facial with a pumous stone.

To fill holes, get a patch kit from spectrum gelcoates for whatever year your boat is. About $22 delivered.

Marine tex is also perfect for this repair from the standpoint of a filler. it an epoxy that stays white when dry and color can be added or you can paint over. I like the marine tex because it has pretty good bonding quality and a bit easier than a west sytems type application. You have to practice with it a bit becuase first time out you will end up with it on every finger.

If you decide to use Marine Tex, you may wish to buy several 50cc syringes (without needles)from your local pharmacy or medical supply place. The syringes make it much easier to apply the material where you need it as you can fill the small holes from the bottom up without getting the Marine Tex all over the exterior margins of the holes.

You might be able to do the same thing with those bag-like things (technical term) that bakers use to apply cake frosting, but I've never tried it.

You can also make a bag like thing (I don't know what they are called either) out of a zip-lock bag by loading a corner and cutting the tip to the right size to squeeze out the stuff. Joe

Using a hypodermic needle and syringe is a good suggestion, particularly when trying to fill holes that are in the horizontal plane, i.e., where gravity will not tend to flow the filler to the bottom of the hole.

One technique I have seen recommended:

--place tape over hole
--pierce tape with needle
--inject filler (epoxy)
--quickly remove needle
--place a second piece of tape over needle hole.

This may allow you to fill horizontal holes which otherwise tend to leak out the filler material as it cures.

When presenting yourself at the pharmacy for purchase of hypodermic syringes, it is best to avoid the appearance of a drug user, as the Pharmacy may decline to sell you syringes. This is at the discretion of the pharmacists.

Thanks for the good suggestions. Worth a try.

West Systems markets plastic throw-away syringes intended for use with things like epoxy - I've usually got a dozen or so of them around - and you can buy them through West Marine and probably a number of other chandleries as well.

There is another inexpensive source for syringes used for glue, epoxy, etc.

It's Vandykes restorers.
