Plastic Classic Forum

I just re-read through your whole thread, you've come a long way! It must feel good to be at this stage after all of your work; thanks for sharing your progress!

Thank you guys very much! I was just questioning whether these were hibernating blisters, or just discolored spots. My concern is that if these are latent blisters, I might need to grind and fill them all. There are a LOT of them! I have this vision in my head of these hundreds of little spots bloss...

anybody? por favor?

Hey all, I realize that these pictures aren't the greatest- but would you guys please let me know what you think of the condition of this gelcoat? There are discolorations everywhere-dark blemishes, and I'm not sure what they are. I have a hunch that they are old blisters which have shriveled up- an...

Thank you for weighing in! The original poster elaborated on his post-it can be found on the link below, if anyone is interested and has not seen it yet.

I just dredged the old thread on the other site, which can be found here.

It strikes me as I write this that I am making a habit of posting some ridiculously novice questions, I apologize for lowering the collective IQ of this board. :)

This is the only time that I have ever heard such a thing, I don't think that its true- if nothing else, just because its' the first and only time I've ever heard anything like it. The idea just kept floating around head as I felt the heat buildup while sanding the failed barrier coat off of my hull...

I found this post in a thread discussing the removal of a barrier coat in another forum, has anyone here ever heard of this, or is it another example of chicken little mentality? "Sanding an older boat to the extent necessary to remove the barrier coat is a really bad idea. That kind of sanding...

I wouldn't presume to be able to speak for anyone but myself, but my impression from reading just about every thread on this board that I thought dealt with barrier coats, thinning gelcoat, or blisters... is that barrier coats do sometimes have a legitimate role to play- if a boat actually HAS blist...

Great answer, thank you!

I know that this is a very old post, but I thought I'd dredge it up as there were some conflicting opinions. Some said that raw glass will definitely absorb water and cause blistering, others said that it is not a big deal. I have some places where I was a little overzealous with the sander, and wil...

ps Peter, I just looked- you have such a cool boat!

Peter, Thanks! I had seen that article in my own research-it was a little scary! Both of my middle chainplates are angled inboard-possibly to avoid the sideways loading that the article spoke of? I guess it worked as the stick stayed up for 36 years now. I emailed Contest to see if there was any par...

Hey classic-plastic-ers, I'm having a hard time finding anything to replace my old chainplates. I think that these were much more common in Europe, but rarely used in North American boats. Westerly used this type of chainplate in their older boats. So far I've found only one place who sells them, bu...

Brian, Thanks for the response. As for your picture... well, THAT is dedication! Such a beautiful boat certainly warrants such meticulous work. I just re-read through your blog, and have to say I'm really impressed with your attention to detail and workmanship. You're doing a great job of documentin...

I have an idea.. I am kind of reluctant to try it, though. Sanding the small area below my teak rubrail is a pain in the butt, my random orbital sander is too large to get in the nook, and my palm sander is useless as it gums up with paint immediately. When doing my 2 part compatibility test, the ra...

Well, I did the compatibility test by taping a saturated rag with Interlux brushing reducer 2333 to the hull. I was worried that I wouldn't recognize the "softened" paint if it was indeed incompatible, but that wasn't an issue. It is amazing how aggressive the chemicals in the 2333 must be...

How disappointing!

I guess I'll just take it into a service center. Thanks for confirming that I'm not imagining the problem... still have a lot more sanding to do =\

Great responses! Thanks! Rachel, The reference to mixing my own compound was my explanation for not mixing up an epoxy/cabosil/microbaloon combination like I have read about on here, I was just going to buy the can of watertite. I was just not sure if the pre-made watertite would be OK or if I shoul...

I posted this to another board, I'd love to hear y'alls opinion I'm almost finished sanding topsides down, not to gelcoat- but to what I believe to be an old 2 part. Is there any way to know whether it's a 1 or 2 part? It is incredibly well adhered, and feels like gelcoat. I am down to gelcoat in so...

Hellooo I have a question. I know from reading that this crowd loves the PC 7335 sander, but has anyone had any experience with the 7345? Mine is going through various stages of kicking the bucket, and I've used it for less than 10 hours or so. It is acting like there is a loose connection with the ...

Thank you for all of the replies. I have to say, I am shocked at the difference in tone between this forum and some others that I frequent. What a novel concept, that people help each other and offer encouragement rather than engage in endless pissing contests. I appreciate you guys very much.

Hello boat gurus, I have a problem. Yesterday I cleaned, dewaxed and otherwise prepped the topsides of my Contest 31 for sanding- but after doing a very small test section, I stopped. I have a new Porter Cable 7335 bought after reading this site, and I am afraid that I am going to take too much mate...
