Have you worked with resins, do you need procedure info
The last time I did anything worth mentioning was 35 years ago when I made a couple of car seat shells so my experience is very out of date. The few times I have mixed resins since, I have had very variable results so I have been looking on the Lotus forum for hints. They seem to recommend the West system
http://www.westsystem.com.au/west_system/ What attracts me is their dispenser system so as to get the proportions correct as I feel this is an area where I have gone wrong in the past. Either too much or too little catalyst.
One of the cracks on the rear skirt had been 'repaired' by the previous owner and I was able to pull the patch off by hand as it had not bonded at all well. This got me thinking that I had better get up to date with current thinking and find out what are the pros and cons of the various materials.
Also I have one small area of stress cracks which I intend to fix with tissue and resin after grinding away the gelcoat. Stress cracks worry me as I have not been terribly successful with repairs to my Lotus. (again 25 years ago). The repairs have tended to shrink over time and become visible. I have thought to avoid this problem by waiting a month or so before applying a final coat.
