I will go ahead and put in my two cents worth here.
From the perspective of one who just purchased a older steel boat in the last year and am currently working through the areas that need attention. Our boats hull
was in fairly good shape with most of the needed repairs
being on the deck
and superstructure. Many of the problem spots were the result of extremely poor design and execution of the pilot house. Like mentioned above with a proper design steel is great, but when the design is an afterthought rust will rule
. Two things I have learned (and read somewhere else) are: Never ever put wood over steel (especially exterior) and weld everything down don't bolt it.
Steel is still fairly cheap
, around a dollar a pound or cheaper depending on where you get it. I bought a wire feed welder and a plasma cutter
when I got the boat and both have had a lot of hours put on them. If you do the work yourself I think it is fairly cheap
. I have spent about $800 dollars on steel so far and am getting pretty close to being done with the repairs
. Once they are done I don't foresee buying
steel for sometime to come.
I have found that Pettite Rustlock works good for a primer, Amercoat 229t is good and at a reasonable price
. If you need to paint
when it is cold Zero Rust works well also. Just for the record
, the above is my opinion and I am sure there are many other fine coating systems available, and would like to hear what others have found to work well. I am always open to new products.
Hope that helps,
