Bottom repair and repaint

4 posts in this topic

I have recently purchased a 1991 Scout 172 Sportfish that has at least a few coats of bottom paint. The boat has been trailered for at least the past few years that I know of and I will continue to trailer it with no plans for it to sit in the water. There is some minor cracking/impact damage to the bottom and heavy chipping in the paint where it has been riding on the bunks that I'd like to fix and smooth out. Then repaint the bottom and hull in either the original Scout sand color or in a bright white.

How can I best achieve this goal? My thoughts were to pressure wash and then sand off all loose bottom paint. Grind out the cracks and minor damage and make proper epoxy repairs.

But then I am not sure of how to proceed. Am i stuck with more bottom paint or can I use an epoxy primer over everything, maybe then some fairing filler over the epoxy primer where its might be needed, spot prime the filler and repaint ?

Any advice and specific product recommendations would highly appreciated.

Yes, you will need to remove all the bottom paint.  Make the needed repairs.  I would fair the repairs with Total Fair after the epoxy repair. Then if you want to use a regular topside paint on the bottom (so long as it doesn't stay in the water more than a day or two) you will want to apply 2 coats of Total Protect Epoxy Barrier Coat Primer, sand smooth, clean and apply 2 to 3 coats of a topside paint.

Thank you. 

Is 100% removal of the existing bottom paint necessary or just the loose material sanded and feathered out where it's chipped and rough?

You will need to remove all the bottom paint down to gel coat.  Slight discoloration is ok but paint removed.
