Pressure washers
Pressure washer probably not a bad suggestion, but a couple of cavaets.On the principle that big is good, and bigger yet is better, be careful with any pressure washer. The pressure needed to strip the paint off your swimming pool will put a hole in the radiator of your car when you're trying to get those hard to remove bugs off your bumper!The military uses a pressure gun for innoculation/vaccination when they have a lot of people to do at once. It blows the serum right into your arm and usually doesnt even leave a mark or drop of blood. A pressure washer, even a lower psi one, can have a similar effect on one's body. Witness the five page instruction manual, four pages of which are about what not to do.Also, fiberglass/gelcoat is porous so use the lowest pressure you can to do the job. You can actually cut into things with high pressure and a small spray orifice. I remember the guy who pressure washed his house, stripped every inch of paint off it down to the wood, and had to wait months before it dried out enough for paint to stick to it!Tool rental stores all have 'em, and then you don't have to remember to drain it well for winter storage.Personally, I find that I do less damage to things if I use the mildest chemical or system and more elbow grease. Kinda like the time I thought the belt sander would make short work of my project versus hand sanding. It did! Guy
