I have a question for hull refinishing. I have a 30 foot Trias (sailboat) I have been restoring for 1 1/2 years. The hull was crazed (cracked) and had tiny pinholes in it from a lighting storm some years back when my father had it on Long Island Sound. It sat here in South Florida for 7 years exposed to the elements. I got an epoxy primer (CM-15) from Epoxyproducts.com which was recommended by the guy there. He said it is a high build epoxy primer that will fill the pinholes and cracks and produce a good base for a new finish. CM-15 is the stuff folks paint water towers with. He sent this to me due to my current location (south florida) and I was applying the stuff to the entire stripped hull in spring/summer heat. Well, let me say I will never buy the stuff again, not at all sandable. the port side above the water line did not dry solid even after 2 months of curing time. I had to burn off the hard gum with a torch and scrub that area with acetone. Not fun. Re-applied a little cm-15 to that area and sanded the hull as best I could (had to go with 40 grit sandpaper to get anywhere in reasonable time, 3 months. and finally got through the grits to 220 puttying inbetween.) Dark blue went on this past weekend with my hvlp gun thinned to 6% and imperfections screamed out at a 2 foot glance. That was the first base coat. I think it is fixable The remaining pinholes I could not have seen or felt with white and canary yellow (cm-15) hull color. <br /> <br />My question is...can I apply a glazing putty and mix some of the base coat (interlux brightside dark blue) with some it or westsystem to squegee in the imperfections and pinholes ? <br /> <br />The interlux decription of brightside is that it "hides well". I guess that means after 3 coats brushing on and heavy wetsanding. I plan on 1 - 2 more coats of base (interlux brightside dark blue) and then I have a gal. of Clear Acrylic Poly to go over that for added uv protection and a supergloss finish. 3 coats or so depending on wetsanding results (The Clear is another epoxyproducts.com item.) I was told I don't need to prime. That is what the epoxy primer is for. <br /> <br /> <br />Thanks in Advance

I have rewritten this response a half a dozen times trying to make it sound nicer. I'm not having much luck.<br /><br />Now we're up to try number 7.<br /><br />Deleted that one too, now we're up to 8.<br /><br />Look, just sand that trash off of the hull and start all over. <br /><br />As nice as I've tried to make this I still have to say one thing: <br /><br />Quit trying to mix up some magic crap to try to fix your problem. When I saw you say "My question is...can I apply a glazing putty and mix some of the base coat (interlux brightside dark blue) with some it or westsystem to squegee in the imperfections and pinholes?" I though I had finally seen the very worst idea ever posted on a boating message board. Do not do it.<br /><br />Go to one of the major paint manufacturers, Interlux would be as good as anyone, and commit to using their suite of products. Read all of their literature and then follow their instructions to the letter. DO NOT try to substite other products at any stage of the game and DO NOT mix up your own witch's brew to try to fix problems.<br /><br />I'm sorry to see you got royally screwed on the trash you bought. I have to say thought that it is your own fault. Its a boat. Buy boat paint for it. The next time your water tower requires painting go back and buy some more of that **** you got the first time.<br /><br />Thom

Well, since I do not know the condition of your boat and/or if you plan on racing it or whatever. Sure, you "can" do anything, but if you're telling us the stuff is crap, maybe you should heave the supplies and start over. <br /><br />Your case is as good as any as to a reason to find a good local marine paint dealer, go in and pay the extra money (versus internet shopping) and talk paint with a professional......

Re: Imperfections after Base Coat, Dark Blue

I had a similar problem with a small sailboat that was given to me. It had been painted over the gelcoat and the finish was terrible. Drip, runs and pinholes all over. I sanded off the paint and found fiberglass repairs where too much hardener had been used and again pin holes all over. I used red lead to fill the pin holes and then wet sanded. After the first coat of paint revealed more imperfections, I applied more red lead and sanded again. I then applied three coats of Rustoleum Top sider paint sanding between each coat. I finished by rubbing and polishing the final coat and then applying a coat of good quality wax. The results were amazing. This was a little Sunfish I was repairing for my boys to play with. When we brought it to the beach and put it along side other Sunfish of newer vintage, it looked better than most.<br /><br />After one season, the finish has held up very well.

This is the Absolute Best Advise Possible............<br /><br />In the Painting of Anything, 2 Rules that Can Not be Avoided are,<br /><br />Proper Surface Preparation, Is the Key to a Proper Finish.................<br /><br />And,<br />Use only 1 manufacturer's System...........Mixing,+ Matching of chemicals Never Works..............<br /><br />It doesn't matter if it's Interlux, or Rustolium, or God Forbid, Krylon Rattle Cans........<br />Don't Mix Manufacturer's..............<br /><br /><br />BTW, Laoch, Welcome to iboats forums..... Pull up a seat,+ We'll Help you through this...................... ;)

Re: Imperfections after Base Coat, Dark Blue

Thanks L.I. Chuck!! I remember the red lead stuff. I refinished a car door once with a former body guy. We used it after bondo was sanded and again after the red lead was wet sanded. Then again after the first first primer coat. I couldn't remember the name however. <br /><br />As far as the paint. I am using Interlux Brigtside for the base. And like I said It was sprayed on, NOT brushed or rolled or drippy and horrible. It just shows some imperfections I couln't see before. 2 more coats to go. Most of the Epoxy Primer was sanded off. I'd say the majority of the original crazing and pinholes were taken care of with west sytem during the fairing process. <br /><br />I'll admit I did make a mistake of buying from this epoxy outfit. I won't buy his garbage products again. I should have gone with Interlux high build primer. Isn't hindsight beautiful?<br /><br />Cheers

I think International "Prekote" is the primer you should have used.

Re: Imperfections after Base Coat, Dark Blue

Nice Job on that squirt. I'll post a url soon with the restore of Vahine. She'll in her slip End of Jan. But the deck (teak caulk job) and mahogony won't be finihsed nor will there be any new rigging (winches, blocks, jam cleats, etc)installed (it pretty much all needs to be replaced with modern equiptment). I did have to replace some old rotten (black dirt rotten) deck braces as well as reconstruct the top end of the transom. I have pics of it all. <br /><br />Cheers
