Moving on from my frame work, I'd like to strip the layers of paint
from the bottom half (and eventually the top half) of the 1971 Trillium
I have attached some pictures of what I've done so far. It looks like the most recent "refinishing" job was a spray bomb. I thought the original gelcoat was yellow (since there was yellow peeking through) but after some scraping, it turns out there's a deep red beneath that. The top spray paint
and the yellow layer both come off together if you get an edge of a scraper underneath, so I believe they are both aftermarket jobs.
The red cannot be scraped, but it appears there's an off-white under that - But I'm wondering if that off white was original primer and the red was the factory topcoat. It's hard to tell. Some old rock chips appear to have been filled and smoothed off to the same plane as the red. But there are sections where it looks like the red was shoddily sprayed atop the off-white and it may never have been a complete coat.
I'm just wondering how far I need to go in order to get a good surface to repaint on top of? Does anyone know what factory colours were available back then?
A second question: what's a safe but quick way to remove these layers? I know that standard paint
remover will melt fibreglass. I did a test patch using the nasty stuff, leaving it on for under 5 minutes just to soften the very top layer, then scraping and wiping down in order to avoid direct contact with the fibreglass layer. I think that if I'm careful I could continue with this method, but if anyone knows a readily available alternative chemical, I'd like to try it.
Alternatively, has anyone had success with a heat gun?
I did some of this with sanding, but the layers are so thick it will take a very long time, and I fear that I'll sand some actual fibreglass away in some parts while I'm trying to get all of the bits of paint off.
I only need to get this down to a fundamental layer so that I can re-paint - so I only really need to get the loose top layers off (I don't need to get down to bare fibreglass in order to be happy)
ps I just had a thought - since our belly band is totally shot, I'm going to remove it and hope that the original colour is still visible underneath. Based on the crappy workmanship I've seen so far, I would be shocked if any previous owners removed the belly band to repaint. So maybe I will answer my own question!
