Well, the saga continues, and considering this van only needs a tart up in my eyes, it is consuming an awful lot of my time! I've been trying to do something everyday, no matter how small, so I feel like I'm progressing.
The roof at least has it's first coat of silver paint, although it looks more like 'streaky grey' in my opinion. A second and third coat might fix that, the stuff sure has good coverage, I reckon the 4 litres could do half the Harbour Bridge, and I thought the 3/4 of a pint of old Silverfros I had mightn't be enough
The problem of sealing the fabric onto the roof was finally overcome to my satisfaction too. I decided to try injecting the Bondall through the fabric, and so with a 10ml syringe and a No 18 needle I went to work. While this might sound like tedious work I was surprised how quickly and how well it went. I thinned the Bondall, probably more than recommended, so I could draw it up in the syringe as it is fairly thick stuff, then found a little nick in the fabric or just poked it though and started injecting it. It created a 'wet patch' which I then chased with a paint brush to where I wanted it, and by doing a couple of different spots about a metre square I then left it to dry. The next day it was easy to work to the dry edge and do another area. I then went back to areas that had blistered up and tried injecting them and found I was able to sort them out too. When it was all sorted another coat of full strength Bondall went over the top and all the water just ran off so on with some silver. The silver soon showed up a couple of small blisters I'd missed and I'm debating if I'll inject them now with the paint on or let it be.
I decided enough was enough trying to sort out the colour and with my assortment of colour cards chose a colour as close as I could to some original cream I'd unearthed and went and bought 4 litres. I've put a bit on the repaired front windows and the front of the van, but I think my brushwork needs some practice, or I'll take to a roller.
Initially I'd hoped I could get the last dodgy coat of paint off the sides and retain the original paint, which I was confident was in good order underneath. The roof and both ends had to be repainted and I really wanted to retain some of the original paint if I could. So I tried sanding with fine wet and dry, dry scraping, paint remover and the heat gun to try and remove just the top layer, and all were unsuccessful for various reasons. I despaired somewhat as I couldn't even get a good clean patch of the brown to work with for a match, so I decided to take it all off with the heat gun, and do what I could to match the brown, so I spent a couple of hours scraping off paint.
To my absolute dismay, the next day, while cleaning some sealant off the roof edge with thinners, and before resuming my heat gun work, I split some thinners down the side of the van which resulted in the white paint blistering. With a bit more thinners on a rag I was able to scrub the 'new' paint off, leaving an original enamel layer unmarked
Too late now though as I've scraped the living daylights out of the bottom section back to bare timber, so I'm really annoyed with myself that my assumption that the present paint was enamel was wrong. I know thinners is the universal test to determine if it paint is enamel or two pack, it has no effect on them, I just never thought to test it! Doh
!!
At least the offside is unmolested, I've left it be, I'd much rather have the original paint with a few blemishes than new paint so I'll see how it pans out in time as the paint revealed is a later coat which has a pinkish tinge to it rather than the original warm cream colour. Can't see both sides at once as my old painting teacher used to remind me at Tech.
