Hello everyone. I too am a "newbie", having purchased a 1973 Boler about 2 months ago. I would like to repaint the bottom half, however, there are so many different colours of blue on it in what I would guess are a variety of paint types, and white paint or fiberglass showing through in some large stone chips. I don't really intend to strip it but I would like to get it smooth enough to repaint and to look decent. Should I start with a paint stripper for the top few layers and then move into sanding it? I tried sanding it this morning - 60 grit took off paint drips but didn't help with the many coats of paint. What would I fill the chips with if it is required? I have already used some of the tips provided to other members on a number of different items and enjoy the forum very much. Thank you.
When I did my 1300, it was originally 'advocado' but when I bought it, it had some horrible grey/brown paint on the bottom half with some pinstripes on it...
I scraped it off using one of those heavy duty razor blade glass scrapers. I went through about 2 packs of blades but with a fresh blade, you can occasionally get multi-inch runs scraped off and the job is fairly quick... I think it took me an afternoon.
I recommend going right down to gelcoat and then use body filler or glazing putty to fill any scrape marks you may have made with the scraper... If you try to paint over some incompatible paint underneath, you might get buckling (see another recent thread)...
If there are gelcoat cracks, then I recommend wirewheeling them with an angle grinder, then fill with body filler (bondo)... clean up minor imperfections with spot glazing putty (body shop supply store or canadian tire. Comes in a toothpaste tube, dries in minutes, sands smooth. get spring-steel scrapers.)..
