Sherfab unlimited in Ontario Ca
Sher-Fab Unlimited Inc. Your First Choice For Composites they mail order product.
Pretty much clean 100% of dirt, grime, oil, glue...... EVERYTHING from the hull!
Sand until desired flatness for finish, essentially you need to mix the Prestec (I recommend this brand, its pretty much a problem free product!)
roll, brush or Spray it down, it will cure in open air and no PVA (Poly Vinyl Alcohol) will be needed for 100% cure, The manufacturer does not reccoment adding anything for thinning, I have added very small amounts of Acetone in the past (Less than 5-10%) and never once saw any issues, this product as well as the Duratech can be wet sanded for an even flatter finish such as clear on a car, but a very hard surface! so you may want to use a very fine paper before buff to make it easier on you and your knees.
I blasted through this rather quickly, so if I get anything wrong as the internet pro's pop in, please accept my deepest condolences for my Laziness, if there is any more questions, you can get more info from Ron at Sherfab, he will sit on the phone with you and paint a much prettier pic for you, after all, he'll be getting the sale! Their prices are pretty hard to beat these days.
