Lift old patches off with a bit of heat gun and a spatula type tool. Not to much heat once you have an edge to grip use fingers or pliers to help the process. Tease the patch off don't tear it.
I have some Avon grey mayerial BTW which I don't need
Doing the Gluing
what you need to do is very thoroughly prepare your surfaces, they have to be roughed up very well! You can do it with a plastic wire brush in a drill. I'm actually doing this at the moment so if you pm me your number I'll text you some pictures of the roughness.
Bostik 2402 , bodtikure d10 hardener
Plastic wire brush http://www.tooled-up.com/MicroCatego...=3877#prodlist
Roller or heavy scraper.
disposable latex gloves
After prepping the strake tubes wipe down with a rag and thinners. after a while waft the heat gun over the areas to ensure evaporation of thinners.
Masking tape either side of the glue line will ensure no overspill of glue but you want 10 mm width more glue on the tubes than the patch, it comes off easily.
Mix the glue up with a small amount of thinners 10% and hardener, stir for 2 minutes. Paint a thin coat on both surfaces when this dry do it again. previous to this you will have put on 2 pairs of the disposable gloves. It means you can get rid of the top pair when it gets too gluey. When this coat becomes tacky you have to do the sticking
Now that you have gotten wasted on the glue fumes the job becomes a lot more fun. I guess I forget to mention Ventilated work area
When you apply the patch it's a one time hit so you need to get it right.. when it's in place work the heat gun over it and rub it in firmly with the roller.
If you get it wrong start at the top and do it again
PS You find you leaks with washing up liwuid solution or if your'e a diver Snoopy
Cleaning Depending on how grundgy the tubes are I'd use thinners or TFR rub it on wash it off quick
