I recently acquired 4 18" scoop bins at an absurdly cheap price
due to reclaim of storage space.

Unfortunately, they are made of High Density chipboard,
and covered with aged vinly covering, but have good dimensions and are VERY,
VERY solid.

My "Sound Guy" I took with me to check them out before buying them, said it
would be worthwhile to strip the vinyl, and spray them with fibreglass
resin.

I am in E London.

Q1. Where can I get fibreglass spray in London?
Q2. Is it better to paint boxes first, then spray/paint on resin?
Q3. Would it be cheaper for a cabinet maker to do it ?

Thanx in advance.
