Would this b ok???

would it b ok 2 spray paint some aluminum foil flat white? B/c i have jus a lil bit of al. foil at the top of the grow sec taped to the light fixture. The rest is jus some cardboard spary painted flat white...i have the al foil at top to make sure to trap as much light as possible... thnx in advance

if the foil moves or bend, the paint will peal off.

hmm...nice point..will try something else... thnx for tha feedback
