Justin, I need some advice

[Tom Ehmke]

I read a response that you gave to someone about a week or so ago that dealt with high build primers. I am on the final leg of finishing a rudder repair on my 272 and want to use 2-part Interlux to paint it.To summarize the repair, I decided to bore out and epoxy the holes in the rudder where the pintle straps are bolted on because of the results of compression. Over the years the rudder has slowly collapsed from tightening the bolts on the Foss Foam rudder. R.W. steered me to West Systems and I bought the epoxy and necessary fillers to make the repair and fair the rudder. Now I am at the final stage before painting and I have faired and sanded, but the surface is not quite where I would like it to be. Will the high build primer (one or more coats) and some light sanding prep the surface for a quality finish? I'd appreciate any advice here. I only want to do this once if you know what I mean..Thanks,Tom

Tom,

Interlux recommends to sand the primer until it is translucent.r.w.landau

Fairing

Tom - Fairing is one of those things where there really is a 1:1 ratio of work in to finished quality. West system with fairing mix is the stuff to use if you can still feel any defects. If that is the case, I would put on one more layer of West, filling the depression until its slightly proud of the surface, then sand back down with a block big enough that more of the block is on the rudder than is on the repair so that you get a good transition. Then I'd do the high build primer - high build in this case is really only a few mils. Its enough to get rid of paint to glass transitions etc but not enough to fill depressions. Put it on, then sand it down until the epoxy just starts to show - translucent as RW puts it - the color coat. Justin - O'day Owners' Web
