Hey! I'm kinda desperate. I'm cleaning this boat and the guy wants the "film" or the nasty crap that forms at/below the water line cleaned. Any tips on how to do this? I've got about 4 days total to do it. I'm on a limited budget also. And help would be appreciated thanks!
P.S. It's a hull that is similar to many high end bass boats. It's actually a speed boat though.

I know this may not help you, but on my boat, I always put on a heavy coat of high quality boat wax at the start of every boating season. It helps a LOT in keeping that stuff from clinging. You may try that or go down to your local boating supply shop and look over their selection of cleaners. I am sure you can find something in your budget that will do the trick with a little elbow grease!

Well, this is how I detail boats with gelcoat finishes and scummy bottoms. I use a cleaner with muratic acid or other form of acid, can be found at any boat shop. Depending on boat size, 1 gallon should do upto a 21-24' boat if used only below the waterline. I use an insecticide pump/pressure sprayer(hardware store) with hard plastic bushings/gaskets(acid) to make the most out of the product and reduce hand fatigue from a hand sprayer. I try to get the product on quickly and then rinse spray canister with fresh water so it lasts longer. Let the acid "work" for about 5 minutes and you should notice the scum drooling off. This is the cheapest route if it works for around $20-25. If not rinse well, dry and then use a high speed buffer with foam pad and a good brand of polish(I prefer 3M). Since it should be gelcoat, it is much more forgiving than automobile finishes and a higher rpm can be used to remove what is left. All but the most stubborn stains should be off by then.
As a side note, if you are going to use the acid, where a breather mask, safety glasses, rubber gloves and long sleeve shirt/pants for obvious reasons. Also, the acid doesn't damage the gelcoat, but it can damage the boat trailer's finish with premature rusting from experience:( if not rinsed off immediately. I used to detail most boats on a hoist at local Marinas where they were kept to avoid damaging expensive boat trailers.
Good-luck!

Muratic acid is correct.
I have had different boats starting in 1978. The muratic acid will clean of all the old scum. Be careful and follow the directions given in the above post.
3M Finessit (sic) has been very good to use with an electric buffer to make everything look like new. Then use a good marine wax like 3M for protection.

Mary Kate makes some stuff called ON/OFF. You can get it at most boat supply stores. There is probably muratic acid in it. Its good stuff. Pretty toxic though so follow the safety precautions. Its relatively inexpensive too (under $10).
